Foot What muscles work. Anatomy of the muscles of the foot

Today we will talk to you about the anatomy of the muscles of the legs, how they work, what kind of muscles and at which movements are strained, as well as look at the exercises that will help you swing your legs. You will also be published to familiarize yourself with the previous article about.

Anatomy and structure of man legs

Oddly enough about legs in gym Forget almost everything. There are hands, chest, muscles of the back and press, but the case comes up to the legs.

Perhaps because they are less common in sight of the strong half of humanity. In women, things are a little better with this, all the same legs - one of their main trumps in appearance. But, nevertheless, and others should recognize the anatomy of their feet.

So, consider, from which groups our limbs are:

  • Screw muscles.
  • The front surface of the hip.
  • Rear surface of the hip.
  • Muscles of the buttocks.

In each of these groups, separate muscles are separated. Now let's talk about them.

More about the structure of the legs and the features of their workout

The muscles of the buttocks include greater, middle and small buttock muscles. Large jagged muscle is responsible for the form of your priests, average and small muscles Large, affecting the tightness of this body.

The most good and most effective exercises for these muscles are rightfully considered to be the lifts of the pelvis lying on the back. All these exercises can (and even need) to do with weighting, in some cases gradually increasing weight.

The biceps of the hip, semi-steerly and semi-dry muscles can be attributed to the muscles of the back surface of the hip.

The training for these muscles is better to spend at the beginning to work out their better, since they always remain without due attention. In the work on them will help you exercises like deadlift, Enclosures of the housing with fixed legs, bending legs lying with weighting.

Retreat from the topic: Look for the best exercise to train the inside of the hip -!

The muscle group of the front surface of the thigh is presented primarily by the quadriceps. It takes almost most of the front of the hip and includes: lateral, medial, intermediate and direct muscles.

In addition to him in this group there is a comb, long leading, tailoring and thin muscle.

Popular exercises for this muscle group are squats with a barbell on the chest, the animals of legs from themselves and flexing the legs sitting with a crayler.

The leg muscles include calbal, chibaloid, plantar and front tibial muscles. The calf and camebaloid muscles are in each other and are the main muscles forming the skin relief.

With the help of legs, a person moves in space due to the complex structure. In a mutual location, a person has bones, muscles that depart from them tendons, as well as joints, nerves and vessels. Nature has created a foot in such a way that during walking there is a minimum load on the organs.

Despite the complexity of its structure, the foot has four departments. The first is called the "belt of the upper limbs" and includes the bones of the pelvis, the second - the thigh, the third is the shin and, finally, closes all the foot. Topographic classification, its most often uses clinical practice.

First department

The beginning of the leg takes from the belt of the lower limb, which are the bones of the pelvis, it is fixation with them that hip joint, it is formed by the head of the femoral bone. The pelvis consists of two bones of the pelvis and the sacrum, with which everything is connected to the back. The bones of the pelvis include a pubic, sedlicated, iliac bone, the bodies of which they grow in the field of the godded depressure about 16 years.

The entire bone frame is covered with muscles, they can move away from the pelvis, reach the hip. Some muscles overlap one another to ensure the movement of the hip joint and strengthen it. Numerous vessels are published from the small pelvic space to the lower limb, the nerves are located nearby, they have their anatomical features.

Start correctly describe the structure of this part of a person's legs follows from the femoral bone. In any person, the right or left lower limb has the same structure. Features are that the femoral bone is the largest formation in the skeleton. IN vertical position It can withstand a significant weight due to its unique structure.

Bone base

The structure of the thigh will be incomplete without bone base - femoral bone. It has a body, two ends, one of which takes part in the formation of hip joint. It distinguishes the head, neck, two spit (small, large) - all these components are involved in the formation of hip joint. The hip joint capsule is additionally strengthened by bundles. The ligament has such powerful, which prevent dislocation and are able to withstand body weight.

The body of the femoral bone is a durable tube curved at an angle. The walls of its thick and strong, inside contains a yellow bone marrow. Bundles of the joint are attached to the body of the femur, muscle tendons that ensure the movements of the hip joint.

The lower part of the femoral bone is involved in education knee Sustava. The body smoothly goes into the sideways, on the sides of which the supermarkets are located. There are articular surfaces, which are two articular articles with clippings in the center. Bundles, muscle tendons are attached to all bone protrusions. Unlike the hip, in the knee joint, the capsule is fastened along the edge of the articular surface, and the patella is located in the front.

This bone is the biggest seamovoid, it performs in the form of an additional lever, which is woven into the tendon of a four-headed muscle. Inside the surface of this bone, a person is smooth, which provides a gliding over the surface of the thighs of the hip.

Muscles

Anatomy of this department, in addition to the femur, includes more muscles. The fleshy part of the red color is muscle, and the white part is a tendon. This binding link that connects the bone and muscle fibers. Precisely thanks to the muscles, legs have beautiful shapeIf they are constantly in good shape. The main ones are:

Vessels and thigh nerves

It has this site its features of blood supply and innervation. Vessels and nerves occupy special spaces between muscles that help to navigate. The biggest artery is the femur, there is a vein next to it, which has the same name. The features of the artery are that it originates from almost the aorta and has a colossal pressure in its cavity. By occupying certain spaces, it gives the branches at nearby education.

But in the area of \u200b\u200bthe rear department, the largest nerve passes, which is called the sedlicate. In addition to him, there is her female nerve, which is located in the field of the internal department, and many others. All of them provide sensitivity, innervate muscles, due to which movement occurs.

Shin not just beauty

After the femoral bone and fabrics should be shin, which contains its anatomical formation. As in the femoral area, there is also its skeleton, muscles and tendons, as well as blood supply and innervation.

Skeleton

The leg part of the leg includes two bones: one that carries the load, wears the name Tibry, the second is a small bertovaya. The first participates in the formation of the knee joint, for which there is the corresponding articular fields on the top platform, called the toilets. In the area of \u200b\u200bthis dice there are projections to which tendons are attached. Mulberian bone is being strengthened somewhat lower and does not accept participation in the structure of the knee joint.

The human bone of the legs form a fork that covers the block of the tone. On the sides in the joint there are ankles, one internal, and the second outdoor. In the middle part between the bones, a tendon membrane is stretched, which limits the anatomical spaces.

Muscles

In total, there are twenty muscles in the field of shin, they provide movement, performing the foot of the movements. Any person in the area of \u200b\u200bthis department they allow you to raise or lower the leg, make the movement with your fingers. Some muscles originate behind the knee joint, end in the foot area.

There is also a topographic classification that allows you to split all the muscles on the front, outdoor and rear groups. The front group is responsible for the extension of the fingers and feet. Outdoor, or small, allows you to perform movements in the area of \u200b\u200bthe outer edge of the foot. With the help of the rear it becomes possible to bend fingers and foot.

In the area of \u200b\u200bthis department, the most powerful is the icy, it originates from the heel in the form of Achilles tendon. Next follows the muscle itself, which is clearly visible under the skin, forming a characteristic relief in humans. Her features are that it consists of a double-headed, which, in fact, is visible, as well as a Cambalo-shaped, located under it.

There are also long flexors and extensors of fingers that provide movements with fingers. Of course, they are not so complex as on the brush, everything is associated with their functional purpose, which consists in the support.

Blood supply and innervation

The vessels and nerves of the legs take their origin from those who pass on the hip. They fill certain spaces called channels. Blood supply is provided at the expense of the front and rear tibial artery, which is separated from the poning.
In turn, the knee joint is bustling with eight arterial trunks. The veins in the area of \u200b\u200bthis department are two (one large, and the second small subcutaneous), which are connected to a plurality of small veins, ultimately flow into the poverty.

Innervation provides a tibial nerve and a small -com nerve, which depart from larger trunks. They innervate muscles, and sensitivity is provided by skin nerves.

Stop - Support and Stability

Due to the foot, it takes a support to the surface, a person has the ability to move as much as possible in space. Total stop has three departments for which the bones are projected: replous, plus and fingers. The bones are replous consist of a tan and heel, which are the largest. Small bones follow them:

  • ladle;
  • cuboid;
  • three cuboid bones.

All bones of this department have their own characteristics, spaces and joints are formed between them with their ligaments.

The bones are plusing are represented by five tubular bones that have a body, head and base. The most massive is the first, but the little one is the fifth.
Then they follow the bones Folang fingers who have three bones in their composition. The exception is the first phalanx, which contains the nail and main phalanx, the rest have an average between them.

Muscular apparatus

In total, the muscles of the rear and the plantar surface are distinguished, which contribute to the flexion and extension of the fingers, the additional maintenance of the vault. On the rear pass:

  1. The short extensor of the fingers of the foot, the task of which is that the fingers move in the toll-lineal joints and dismissed. The muscle gives her tendons from the second to the fourth fingers.
  2. Short extension thumb Not only extension it, but also assigns the dust.

On the plantar side, the muscles have their own characteristics, in the area of \u200b\u200bthis department more. The list can be represented as:

  1. Misinz has its own muscle that takes and flexes it.
  2. There is a short finger bent, the function of which is understandable from the name.
  3. Muscle, reducing the thumb, bends and assigns it to the side, helps to strengthen the inner part of the foot of the foot.
  4. In the area of \u200b\u200bthis department there is a short thumb twin.
  5. Drawing muscles also contribute to the bending of the fingers.
  6. The short little margin flexor not only bends this finger, but also assigns it and helps strengthen the foot of the foot.

Between the tie bones in the area of \u200b\u200bthis department also have its own muscles. They are located on the back surface, occupying spaces between the bones. In addition to the fact that in the area of \u200b\u200bthis department, they strengthen the arch of the foot, occupying their spaces, they contribute to the movement of the fingers.

Blood supply and innervation

Certain spaces occupy the vessels and nerves on the foot. In the sole area there are several arterial arcs that provide normal blood supply to fabrics when the foot loads are loaded. A larger number of nerves focused in the rear area, this site is most sensitive.

The structure of man's legs is so complicated that ensures the highest possible functionality. All components are in close relationship, carrying out certain functions. If any component fails, then the work of the whole leg is disturbed.

Surface anatomical muscle satin human body Take another 8? 9 classes. People who came to the world of bodybuilding and bodybuilding are detailed by studying the structure of muscles, be it a novice athlete, a practitioner coach or an advanced "pounder". After all, without anatomical knowledge of the principle of work muscular groups It is impossible to choose the right exercises for heavy training with burdens.

The muscles of the bottom of the body are the most bulk group of muscles, which account for more than half of the muscles of the whole body. Their condition and tone largely determine human health.

Anatomical "building" foot muscles is conditionally divided as follows:

  1. muscle berry group;
  2. quadriceps (front of the thigh);
  3. muscular group of the rear surface of the hip;
  4. a group of shin muscles.

Buttocks

The development of the fifth point has always been and remains the subject of admiration for the opposite sex. But besides the object of physical beauty and aesthetics, jagged muscles Must be an inseparable part of the pumped muscles of the body. Without developed buttocks, it will not be boasting a strong back, nor elastic beautiful feetnor competitive power indicators In fitness.

  • Large buttal - the largest and thick muscle in the structure human organism. It is from its thickness that depends appearance (not roundness, but "meatiness") priests. The muscle performs a number of essential functions, the main ones are the extension and rotation of the thigh, straightening and fixing the body.
  • The medium isodic is the outdoor pelvic muscle. Among the basic functions that it performs is to lead the legs forward and backward, the body stabilization during extension. Better exercise For pumping beams of this muscle is squatting with burdens.
  • Small beetal, as the average is located in the upper area of \u200b\u200bthe buttocks and is largely overlapped with the main buttock. The lead to the side to the side is the function for which this muscle is responsible, respectively isolated exercise Legs load small berries most.

Front thigh surface: quadriceps


In the photographs of the muscles of the legs - quadriceps


Units are gifted by nature with slender attractive hips, the rest has to regularly catch the beauty of their legs with exercises with weights. To achieve ideal proportions, you need to know the anatomical design of the muscles. The front part, and a piece of the side surface of the thigh, occupies a four-wheel thigh muscle (quadriceps).


All four heads are treated as independent muscles:

  • The straight muscle closes most of the three other heads and from all the muscle bunches of the quadriceps is the longest.
  • Lateral wide muscle is almost the entire front-flying outer surface of the hip. It is hidden in front of the impact of the thigh, and it is almost unallowed from above behind the straining wide fascia.
  • The intermediate wide muscle is "crowded" between the rest of the muscles, the development of its always lagging in the quadriceps.
  • Medial wide muscle passes through the inner bottom of the hip. Its location is fixed on the front and medial areas of the lower half of the hip.
Classic squats, Bulgarian priest, cried with a definition - not all exercise options for quadriceps of their dreams. Sport makes muscles with relief and elastic, flabbiness and fat excess disappear.

Hip - Rear View


In photographs of the muscles of the legs and buttocks - rear view


The rear surface of the hip is the place where the most accumulates in women and the shortcomings of men appear. Its training will not only lead muscles in the tone, but will reduce the likelihood of development of ligaments and joints.

Muscular fibers of the hip back surface consist of:

  • Blood muscles hip. Biceps of the thigh is located lateral on the back of the foot.
  • The semi-drying muscle, which begins along with the long head of the hip biceps from the sedellastic bulb.
  • Semi-steerly muscle starting from the sedellastic bulb. She turns his shin inside and extensions the thigh in the hip joint with a broken knee joint.
The rear part of the thigh leading muscle in good faith fulfills its supporting role. Together with the short head of the two-headed muscles, it works on bending legs in the knee (pulling up the heel to the buttocks) and curing her back while walking and running.


To the muscles of the lower legs include:
  • The calf muscle formed by the medial and lateral heads, which are connected in the field of the tibia and go to the heel bone.
  • Cambalo-like muscle. It mainly consists of slowly shrinking muscle fibers, which are inferior by the strength of rapid, but they have great endurance.
  • The soles are a small muscle with long tendon. Some people do not at all.
  • The front tibial muscle originates from the tibia. She is responsible for extending and suspending the foot.
The muscles of the leg is the division that performs the function of holding and transfer the weight of the entire body. Also, the muscles take on "responsibility" in raising on socks and plantal bending in the ankle joint, and the ion-colored muscle also participates in the bending of the knee.

All "For" and "Against" in the foot training

A very frequent problem of newcomers in the world of heavy sports is undeveloped legs. Most young bodybuilders and bodybuilders make an emphasis on the training of "beach" parts of the body - press, breasts, hands. While the importance of the "Foot Day" professional athletes above all.

Pluses of foot training:

  • the human body always strives for symmetry, so the pumping of the legs will strengthen the progress of the torso increase;
  • aesthetics are beautiful rounded shapes and a proportionally developed body;
  • good testosterone emission, which contributes to an increase in progress;
  • the center of gravity is reduced and stability improves.
Among the minuses of training legs can be allocated Only the risk of joint injuries. But these are "possible" problems, and not necessarily people who regularly load their knees are in the "risk group". There is also a chance to miss the growth of bones in length, this minus is mainly for young guys for up to 20 years, which still takes place.

Read about exercises for pumping feet.

Walking is an automated motor Act, carried out as a result of extremely complex coordinated activities. skeletal muscles Torch, lower extremities. Human walking is made up of individual steps, representing a simple locomotor cycle, where two phases are distinguished:

  1. Transfer.
  2. Supports.

In the transfer phase, the foot transfer in the air to the more distant position occurs. In the phase, the foot support is in contact with the surface on which a person moves. At the beginning of the transfer of the lower limb forward(The so-called postposition phase) The following movements occur (Fig. 1a):

  1. The flexion of the hip joint, which is carried out with the help of a lumbly-ileum muscle.
  2. The bending of the knee joint with the agreed effect of the two-headed muscles of the thigh and the sedanistic and femoral muscles (semi-steerly, semi-dry muscles, and the long and short heads of the blood muscles of the thigh).
  3. Flexion ankle Sustava With the involvement of the muscle-flayers of the ankle and the anterior tibial and tertiary little metal muscles.
  4. Foot Impretten Foot Muscles Foot Muscles Foot (long finger extensor, long foot extensor, short finger extensor, short foot extension foot).

For the initial contact of the foot with the surfacethere are such processes as (Fig. 1B):

  1. The end of the hip flexion process is a lumbar-ileum muscle.
  2. The extension of the knee joint is a four-headed thigh muscle.
  3. The end of the flexion of the ankle joint with the muscles by extensors of the fingers of the foot and the bends of the ankle joint.

At the moment when the carrying leg completely relies on the surface, then there is a persistent effect of the four-headed muscles of the thigh and the start of the work of a large jagged muscle (Fig. 1C).

Fig. 1. Human walking phases

The next phase of walking is transferring the body forward. Here we observe such actions (Fig. 2a):

  1. The extension of the hip joint by means of the impact of a large jagged muscle and sedanistic thigh muscles.
  2. Antagonism synergism with a four-headed thigh muscle.
  3. Flexion of the ankle joint with muscles-flexors in synergies with a large one-year muscle.

In the process first motor push before supporting two legs There are such processes as (Fig. 2B):

  1. The continuing extension of the hip joint is a large jagged muscle and satellite-poor muscles.
  2. The continuing extension of the knee joint is the thigh tongue.
  3. The extension of the ankle huts with a two-headed thigh muscle and foot folders (long finger flexor, long and short feet of a thumb, short finger bent.).

In phase second Motor ShoneAccording to the human carrier foot with full extension, while the fluid limb is going to step onto the floor there is an increase in the action of the four-headed muscles of the thigh, a large bodied muscle, the sedlication and femoral muscles, the two-headed muscles of the hip and the muscles-flexor foot feeders (Fig. 2c).

At the beginning transition with one carrier limb to another There is a process of shortening the transferred limb due to the reduction of the sedlicate-femoral muscles and the muscle-flexors of the ankle joint, as well as the flexion of the hip joint of the lumbar-ileum muscle (Fig. 2d).

In the process movement of limb in frontthe effect of the lumbly-ileum and four-headed muscles of the thigh with the relaxation of the sedlication and femoral muscles is enhanced. In revenge, this is the extension of the knee joint by reducing the four-headed muscle of the trouble and raising the footsteps of the foot of the foot of the foot (Fig. 2e). Next should be the beginning of a new cycle.

Fig. 2. Phase walking

Muscles of legs are not the only muscle groups that participate in walking.

To hold a person's body in an inclined position, the muscles of the rear surface of the body are reduced when transferring the legs:

1. Trapezoid muscle.

2. The widest muscle of the back.

3. The rhombid muscle of the back, which consists of a large diamond muscle and a small diamond muscle.

4. Muscle, straightening the spine.

5. Long back muscle.

In order to prevent the body falling back at the rear step, the muscles of the front of the body of the body occurs, to a greater extent it concerns the abdominal muscles:

  1. Straight abdominal muscle.
  2. Outdoor abdominal muscle.
  3. Inner oblique abdominal muscle.
  4. Cross muscle abdominal.
  5. Square muscle lower back.

Muscle data also work in case you need to fix the pelvis and provide a support for the end of the leg forward.

Please note that in the process of removing the legs of the body, along with the pelvis makes a turn around the vertical axis in the direction of the support leg. For this, an inner oblique muscle is strained from the support leg, and from the opposite side - the outer, cross-oest and iliac-lumbar muscles.

The muscles that straighten the spine helps to reduce the deviation of the entire body into one of the sides (muscle, straightening the spine) and the longest muscle of the back.

In certain cases, it is possible to observe the rear muscles of the neck. In addition to the already mentioned torso muscles, the following muscles need to be noted:

1. Rear staircase muscle.

2. Muscle lifting the blade.

3. Upper rear gear muscle.

4. Head muscle and belt muscle neck.

5. Semi-loving muscle head.

6. Semi-loving muscle neck.

The work of the muscles of the upper limb with the usual walking is insignificant. During the movement of the hand, the thrifter muscles are reduced in the shoulder and partly in the elbow-th joints, and during the movement back - the muscles of the extensors in these joints.

To the muscles of the shrill flexors include:

  1. Front of the deltoid muscle.
  2. Big thoracic muscle.
  3. Kryvoid-shoulder muscle.
  4. Two-headed shoulder muscles.

To the muscles of the extensor shoulder include:

  1. The back of the deltoid muscle.
  2. The widest muscle of the back.
  3. Lock muscle.
  4. Small round.
  5. Big round.
  6. The long head of the three-headed muscles of the shoulder.

Muscles-flexors of the shoulder joint:

  1. Shoulder muscle.
  2. The shoulder muscle.
  3. Two-headed shoulder muscles.
  4. Long extensor of the ray-tank joint.
  5. Lock muscle.
  6. Round Pronator.

Muscles-extensors elbow Sustava - It is a three-headed shoulder muscle.

The work of the muscles regulates the pendulum movement of the free upper limb, which is possible as a result of one alternate reduction in the front and rear parts of the deltoid muscle.

When all the listed muscles do not have problems with stretching and abbreviation, then a person walks and runs correctly and easily. Such people in the world are very few. Basically, muscles have certain defects associated with some kind of muscle sites. The swelling of the muscle site does not give it to stretch completely.

Inside muscular fiberwhich is not fully stretched, there is a shift of muscle cells in one place and a decrease in the amount of mitochondria, which produce energy for complete muscle stretching. Depending on which muscles are echoes, and which remained normal, these or other defects are left: incorrect gait, uneven legs, gait on the socks, curvature of the spine.

for example, muscles of the back, hands and legs do not move with tetraprezé (one of the forms).

The lower limbs perform the support and motor functions. When the low support moves high, that is, on the back, the upper limbs or buttocks, the work of the muscles changes together with the change in the direction of thrust. The character becomes another and when moving one or another limb.

The article discusses the general and structure of the muscles of the person's legs in particular.

Bones and joints

The durable bone base of the lower limbs provide the femoral, large and the main load accounts for them. At the same time, the biggest bone is the biggest, both in this part. Small and bertovoy together make up the shin, and the bottom is located below, where the bones have a complex structure with a large number of small bones. Between them are joints, thanks to which the stop becomes so mobile. It allows a person to occupy a stable position.

The largest joints in the legs are hip, ankle and knee, each of which is responsible for any movements. If they begin to function incorrectly, the movement is difficult, and it can even become impossible at all.

Blood vessels and nervous endings

Lower limbs need a lot of oxygen and nutrition. Therefore, an extensive vascular system is developed here, providing this part with blood. The main vessel here is the femoral artery. All blood B. lower limbs Provided through it. Next, it branches into a plurality of twigs forming ultimately a capillary network. Vienna repeat the course of the artery.

Without nervous impulses of movement would be impossible. Nerves are suitable for muscles, activating them if necessary. In general, the structure of the muscles of the person's legs (see the photo below) in particular is based on the same laws as the whole body. Therefore, during damage to the nerves of movement will be broken, up to the occurrence of paralysis.

Such is in this part of the human anatomy. Muscles of legs, their structure and location Consider now in more detail.

Muscles

Are more powerful compared to the muscles of the hands. But, on the other hand, they are not so accurate as on the upper limbs. On the muscles of the legs of a person accounts for the biggest exercise stress. For example, the force from the support when jumping from running out of professional athletes is more than six hundred kilograms. Even more loads, they are experiencing when jumping in height, after which the repulsion should be.

In all these and other movements, not only muscles of human legs are involved, but also the muscles of other groups: hands, shoulder belt, torso. Such a load is called global because it requires a lot of energy.

Human anatomy: leg muscles

This muscles are divided into four groups:

    Front thigh group.

    Rear group of hips.

  1. Screw muscles.

    Consider in detail each of the groups separately.

    Front group of hips

    Muscles of man's leg name in this part have "four", as they have four heads:

  • direct muscle;
  • internal wide muscles;
  • outdoor direct muscle;
  • medium wide muscle.

Fouring - this is the most powerful of all muscles on the human body. It passes throughout the front surface, where it crosses the oblique tailoring muscle.

All heads of the four-headed muscles converge in the lower part of the hip in general tendons.

A straight muscle is a two-time and longest. It is expanding the book and reaches the middle of the hips, after which it narrows and turns into a tendon that grows with a prefabricated cup. Located on the front surface, it comes and ends at the Tibial Bud.

The inner wide muscle is thick. It is located on the front-medial surface and from the front edge covers the straight muscle. Inside in contact with the medial group. Its covers the tailoring muscle. Muscle bundles that surround the front-medial surface come forward and down in the oblique direction. In the lower femoral part, it goes into tendon, connecting with the flower of the human foot muscles.

The outer wide muscle is flat, being on the front outer surface. In places it covers the muscle that strains wide fascia. The edge is covered with a straight muscle. Muscle bundles go ahead and down in the oblique direction, covering the femoral bone in front, and below turn into tendon, sticking into it (tendon direct muscle).

The average wide muscle is weaker than four presented. It is flat and the most thin of them and is on the front surface. Average wide muscles Covered straight, starting from the interstal line within it ¾ from above. Bunches are strictly down in the vertical direction, turning into a flat tendon. At the bottom of the thigh, the tendon is attached to another tendon belonging to a straight muscle.

The main function that quadruples the muscle is performed is the extension of the legs in the knee. Two-part muscles involved in the bending of the hip and the tilt of the pelvis.

Muscles of legs whose photos are presented in the article - a complex system of our body.

Rear group of hips

In this part, closer to the sides, there is a two-headed muscle of the thigh. As it is clear from the title, it consists of two heads:

  • long, originating start from a sedlication bulb;
  • a short, emanating from a third of the lateral lip in the middle.

The main function is flexing in the knee of the leg and extension of the thigh. In addition, along with the big one, it will break the torso with a strengthened leg.

Buttocks

This part includes the following human leg muscles:

  • large berium;
  • medium beetal;
  • small berry.

The first takes the entire surface of the buttock. Therefore, the shape of the buttocks is more dependent on it. The muscle takes the beginning of the iliac bone, cock and the dorsal sacral surface. the main task It is to ensure the movement of the hip joint: straightening the torso, as well as leading back legs.

Blow muscles

The calf muscle originates in the femoral bone above the pairs of heads passing into tendon. Then it continues in a massive Achille tendon, which connects with rear surface Pad bone.

Another muscle is called Cambalo-shaped. It is fleshy and thick, located ionic muscle And it stretches into the large part. It originates on the head and the upper third of the mulberry bone, descends over the tibial, without touching the middle third of the lower leg. In the end goes to Achillovo tendon.

The back muscle is represented by the sole, which begins on the sideline of the thigh and the knee joint (capsules). It merges with thin and long tendon, fastening the heels from the bundle. However, such muscles may not be at all.

Many specialists call the ankle muscles with stubborn, as it becomes very troublesome to develop in this part of the body. Long and dynamic loads made the described groups very hardy. Therefore, it is so difficult to develop them even stronger. But if necessary, coaches make up special complexes Exercises and for these muscles.
