Twichever shoulder muscle
Twitting muscle shoulder, m. Biceps Brachii. (See Fig. ,,,,), consists of two heads, in form rounded, spindle-shaped. It occupies the front area of \u200b\u200bthe shoulder and elbow bending and is located directly under the skin.
Long Head, Caput Longum, occupies a lateral position. It begins as a long tendon from the overturning tubercle of the blades, passes above the head of the shoulder bone through the cavity of the shoulder joint, falls into the interbogochny furrow, surrounded misturbing Sinovial Vagina, Vagina Synovialis IntertubercularisAnd then goes into a muscular abdomen.
Short Head, Caput Breve, occupies a medial situation. It starts with a wide tendon from the top of the beak handpiece of the blade and, heading the book, also goes into a muscular abdomen.
Both heads are combined with each other in a long muscle abdomen, which the elbow fossa is narrowed and goes into a powerful tendon attached to the beam bone junction. Attaching the tendon is located double-headed Bag, Bursa Bicipitoradialis, and between the tendons of the two-headed and shoulder muscles, in the upper part of the oblique chord, where it comes to the medial surface of the elbow bone, lies inter-site elbow bag, bursa cubitalis interossea.
A part of the beams in the form of a thin plate is separated from the proximal end of the tendon - uponeurosis Twin Muscles, APONEUROSIS M. Bicipitis Brachii.. Parts from m. Biceps Brachii on the shoulder are located medial and laterally almost symmetrically furrows of the shoulder, Sulcus Bicipitalis Medialis I Sulcus Bicipitalis Lateralis.
Function: bends his hand in the elbow joint and inspires the forearm; At the expense of the long head takes part in the assignment of the hand, due to the short - in bringing the hand.
Innervation: n. Musculocutaneus (with V -C VII).
Blood supply: aa. Collaterales Ulnares Superior Et Inferior, a. Recurrens Radialis, a. brachialis.
Many people know about such a muscle as biceps (double-headed muscle), but few people understand the peculiarities of its structure and the true name. It is extremely difficult to swing hands without this information, so it is advisable to get acquainted with all the anatomical details before drawing up the workout plan. In this case, you can achieve a result in a shorter time.
The two-headed arm of the shoulder is attached to the bones of the blade with the help of tendon. Muscle tissue received its name, thanks to two heads that can be seen in this image:
In the picture, it is clearly seen from what parts is the two-headed arm of the shoulder, namely:
- Short head biceps. This part of the shoulder biceps begins with a bevoid process on the outdoor side of the blade. From her, the muscle passes along the inner surface of the bone to the long head. The short half of the biceps does not have an oblong tendon, but there is more muscle tissue;
- Long biceps head. It is localized on the side surface of the upper limb and begins his way from the protrusion in the area of \u200b\u200bthe blade, which is directly above the deepening of the shoulder joint. This place is called a dish. The long head is quite pronounced tendon, but at the same time a short plot of muscle tissue.
If you take a look at the structure of the biceps of the hand, you can see that both heads are intertwined with each other as you approach the elbow joint, creating a kind of abdomen. It is attached to the elbow using a bicex tendon. Together both heads create a powerful flexor, that is, a flexor.
Function
After studying the peculiarities of the structure of the two-headed shoulder muscles, you can understand what the main functions have. According to its anatomy, the biceps is a limb flexor in the elbow joint and allows you to rotate (inscribe) brush. The long muscle head comes into operation while reducing the shoulder muscular tissues, for example, during the rise of the hands upstairs.
For a complete stretching of the long part of the biceps, the elbows will have to stay back. If you need to load a short biceps head, you need to move a little forward from the body. Such a nuance is useful for beginner bodybuilders, since certain positions of the hands affect the pumping of problematic muscle tissues. That is why any athlete must examine the biceps functions before pumping hands. 
Voltage points
Biceps shoulder during training is constantly loaded and excessive overvoltage, can create voltage points. For example, it can occur during the lifting of the mountain or after the rod bench press. In bodybuilders, the main reason for the appearance of such points is the transfer of greater weight on elbows or elongated limbs. However, ordinary people are also not insured against them. After all, any activity accompanied by severe overloads can cause pain and weakness in certain areas of the hand, which are symptoms of voltage points.
You can learn about their availability by painful sensations in the area of \u200b\u200bthe double muscle. Sometimes discomfort is localized on the front surface of the shoulder. People at the same time pay attention to the restrictions that have not been before. For example, weakness when straightening the hand or the appearance of pain syndrome during palpation of the tendon on which the biceps is attached to the elbow.
To identify such points, the limb should be put on a flat surface in front of them. Previously, it needs to be a little bend in the elbow joint. Then, with the help of feeling, you should search the voltage point.
You need to start the palpation from the elbow hole and gradually move on the tendon to the biceps abdomen.
It should be not easy to poke your fingers, and smoothly lead, massaging the outer and inner side of muscle tissues. In the course of the movement, you can find the seals and there are often stress points next to them. They are usually localized by 1/3 ways across a double muscle. If such places are found, they need to be massaged until the unpleasant sensations decrease.
Pain in a double muscle
The two-headed shoulder muscle usually resistive tolerate loads, but sometimes there is a pain of different character. In such a situation, you need to know the reasons because of which it can manifest itself:
When suspicious symptoms are found in the double-headed muscle, you must contact the therapist. To carry out the survey, it can send a patient to a physiotherapist, a traumologist, a rheumatologist, etc. After identifying the main cause of pain, the corresponding course of therapy is appointed.
Two-headed muscles most people are known as biceps. Knowing her features, you can quickly and effectively pump your hands and avoid injuries that are associated with excess overloads. However, this muscle is in constant voltage, so it is necessary to monitor that there are no strange symptoms. When they identify them, it is necessary to immediately turn to a specialist.
Biceps is a well-established symbol of common muscles. Any athlete will first demonstrate it. This muscle is always in a prominent place and therefore almost every man is interested in her pumping. However, in spite of permanent operation and, it seems, obvious things, few people know that it is generally biceps: its structure, anatomy and a function for our body.
Anatomy
Biceps refer to the two-headed muscle of the shoulder, as it consists of two heads.
- Long Head Blood Muscle Shoulder Located on the outside of the hand.
- Short head biceps Located in the inside.
Both muscles have the same length, despite the names. At the top point, they are attached to the beak blades, and in the bottom - to the elbow joint. Simply put: Biceps is a volumetric muscle that takes up the top of the hand from the shoulder to the forearm.
Function
Biceps hands functions to blend and bending your hand in the elbow. He, as well, helps to rotate forearm and brushes. In daily life, we often interact with the outside world, where you have to raise various items. Due to the fact that the bending movements in practice are greater, the structure of the biceps allows you to perform all the basic physical work. In some cases, he can act as
Anatomy of the muscles of the hands (biceps & triceps): Full livestock with all the subtleties and secrets ...
Hands, people most often imply biceps. However, in addition to the bitsuhi, there is also a triceps and forearm. See the explanatory photo below:
Well, let's understand in order with each component. Let's start, perhaps, with a biceps.
BICEPS
Biceps consists of two heads:
- Long (long tendon, but the muscle is small) is located on the outer part of the hand.
- Short (short tendon, but the muscle is large) is located on the inside of the hand.
Both heads have their origin on the shovel, only in different places ... in other words, both heads are connected in one tendon, which is located near the elbow joint. Subsequently, both heads form a common abdomen, which goes into a powerful tendon (the tendon is mounted slightly inside (to the side of the forearm)), which is attached to the radial bone, and despite their name, both heads have the same length, because the long head on There is a longer tendon with which it is attached at the bottom of the bone.
Biceps bends his forearm and rotates it out (this is supination), it means that besides the fact that the biceps can simply bend a hand in the elbow joint, it can also sip it (i.e., turn the palm toward the thumb).
Through a short head, the biceps takes part in bringing the hand, and the long - hand lead.
In addition to the biceps, the front muscle group of the shoulder, also - the brachial muscle brachialis, which is located below the biceps, as if pushing it out. The main function is the bending of the forearm.
Accent on biceps heads
According to statistics, problems with the development of a short head (the one that is on the inside of the hand) does not arise any problems, it reacts perfectly to the load, and grows well from any hand bending. But, with the development of the long head, the one that is on the outer part of the hand, most have problems!
- In order to fight the outer head (long), you need to remove the elbows as far as possible by the back, just to turn on the outer part of the biceps.
- In order to fight the inner head (short), you need to turn the elbows as much as possible on the contrary.
Grip when working on biceps
- The wider your grip, the more the inner head will work.
- The already your grip, the more the outer head will work.
Brachialis
This shoulder muscle plays a very important role. It is under the muscle (i.e., under the biceps) is involved in most of the work when training Bitsuhi (about 50-70% takes upon itself). It is this muscle that allows you to work with heavy weights in bending with a barbell standing, and not biceps itself.
The best exercises for training biceps:
- Rod rise to biceps inverse grogging
Triceps
Triceps consists of three heads:
- Lateral head (it is external)
- Medial head (it is the middle or small elbow, is near the elbow)
- Long head (it is internal, attached to the blade from behind)
- The outer head begins at the top of the shoulder bone next to the shoulder joint and makes the outer side of the shoulder hand.
- The medial head is on the shoulder bone and partially covered with two other heads.
- The long head begins on the shovel bone and is located on the inside of the shoulder hand.
All three heads are in a single bundle, in the elbow area, and that is why all three heads work simultaneously in all the exercises that engage in triceps. However, each head trains not evenly! Those. Each head receives its degree of load (it depends on the mechanics of performing a particular exercise).
Each of the 3heads (connected, because work in a bundle) But they can be either short or long. This case depends on your genetics. And this, by the way, you can easily check, and find out what you have:
- If your triceps is short, it looks longer and massive.
- Well, if it is long, the triceps looks short with a peak.
According to the type of physique, most often the mesomorph and endomorph are long and massive triceps muscles. But the ectomorphs, on the contrary, most often short triceps with peak. Of course, mesomorphs and endomorphs - the mass of triceps will grow faster, however, the ecectomorphs - the muscles of the triceps will look more athletically from the point of view of aesthetics.
