Despite the fact that the structure of the muscular structures of the arm is in some ways much simpler than the bone structures, they deserve no less attention. This applies primarily to the occurrence of pain in the muscles of the hands. Although in fact, one cannot attach more importance to one or another muscle, because they work together. However, in the human labor activity, the biceps of the shoulder and the triceps experience the greatest load. In more simple and understandable language, they are called biceps and triceps, respectively. The first plays the role of the flexor of the arm in the elbow, and the second - the extensor. In the framework of this article, we briefly consider the structure of the biceps, its functions and other important details.
The biceps, or biceps of the
shoulder, is connected with the tendons and ligaments to the pre-humerus half of the arm. In the upper part, this muscle is divided into a pair of heads. One of them is attached with tendons to the coracoid process on the scapula. The second is attached to a small tubercle of the scapula, which is located above the joint. At the junction of these parts is a synovial bag. The biceps tendons are attached over the radius.
As already mentioned, the biceps of the shoulder performs the function of bending the arm at the elbow, raising the arm. In addition, with the help of biceps, the forearm can turn inwards. As a rule, in people who regularly perform physically hard work or are engaged in strength exercises, biceps are quite developed.
The biceps of the shoulder is the first thing people pay attention to when they judge the physical strength of a person, in particular a man. Therefore, many strength exercises are aimed specifically at
pumping the biceps. Although this is actually wrong: after all, the biceps muscle develops to a greater extent when performing not isolated (lifting the barbell or dumbbells for biceps), but other loads. This happens more effectively during hard training with the use of such basic exercises as pulling up on the horizontal bar, pulling the bar to the stomach, pulling on the block simulator, etc.
Despite its important function and relatively high ability to work, the biceps of the shoulder is very vulnerable. After too much stress, it can recover at the fiber level for quite some time. In some cases, as a rule, due to chronic diseases (tendovaginitis, etc.), with uncontrolled lifting of large weights or with very strong muscle contraction, biceps may break. This mainly happens with a long head. The first symptom is unbearable pain, deformity of the arm in the biceps, etc. The biceps of the shoulder after a similar injury for a long time comes into normal position and returns to the previous level of disability. And even then - only with proper fixation of the tendons and the muscle itself.
Pain in the muscles of the shoulder in any part of them should be eliminated as soon as possible. To this end, competent medical assistance is needed. However, if the pain is not too strong and it is clear that it came after unusual force loads, then you can do without doctor's help. The cause of the unpleasant symptoms is quite simple - the release of
lactic acid in the muscles. This is a natural reaction of the body to muscle overload for their quickest recovery. To eliminate pain in such cases, you can use simple, inexpensive, but well-
warming ointments.
