What is pectoralis minor?
pectoralis minor is a thin muscle located near the upper chest. It is located near the Pectoralis Major, which is located above a smaller muscle. Pectoralis minor is triangular used to move the blade forward and down. It is also necessary to stabilize the shoulder blade during movement. An example of everyday use of muscle would be to push open doors.
The origin of smaller pectoralis is on several upper ribs. It inserts into the process of coracoid blades and its innervation is through the media breast nerve. Towards the insertion of muscle flattening and becomes tendon.
As with many body muscles, pectoralis minor cooperates closely with another to provide the desired movement. In this case, the muscles work with the front of the serratus. While smaller pectoralis pushes forward and down, serratus the front is pushing up. This provides movement that is known as clean stretching - rotation.
The muscle is found in the upper part of the chest and attaches to the surface of the third, fourth or fifth ribs. This varies depending on the person involved. Although the complete absence of muscle is rare, it is not unheard of. In some cases, the muscles may consist of several different parts, although it is also relatively rare. Sometimes there is a variation where the tendon is inserted, although it does not affect movement or strength.
Although pectoralis minor is an important muscle in the chest, pectoralis is larger and stronger. However, both muscles have different actions, although both have the same innervation. Instead of moving the shoulder blade, the purpose of the pectoralis is to ensure the flexion of the shoulders and the adction. An example of this kind of movement could be the use of a role on a deodorant. Tpectoralis The main muscles can be strengthened by clicking.
Injuries may occur in pectoralis smaller, although problems with more likely to arise in the main pectoralis. Chest trunks are relatively common injuries. This may include sharp and sudden pain and swelling over the muscle area.First, these injuries are usually treated by resting and applying ice, although more serious injuries may require other non -surgical treatment. Operations are usually required only if they are completely ruptured.
