Description
Anatomy of a bridge shoulder
- The shoulder has a spherical shape and is located on the top of the shoulder blade. The area from the seat to the shoulder is called the scapular region. The area above the shoulder is called the shoulder region, and the area below the shoulder is called the pectoral region. - The shoulder is made up of three layers of muscles: the neck muscles, the back muscles and the arm muscles. The shoulder region also contains a large arm muscle (triceps) that supports the humerus. - Together the muscles form a dense cover that protects and strengthens the shoulder joint. - The connection between the top of the humerus and the collarbone is called the carpus. - The scapula contains the head of the humerus, which articulates with the humeral fossa in the elbow bone. This area is called the sella. When the right arm is in a horizontal position, the brachialis and back muscles bring the shoulder down. Lymph nodes, blood vessels and nerves are found in the area of the shoulder. The structure of the shoulder of the bridge - As already mentioned, the shoulder is formed from the convexity of the right shoulder blade above the collarbone. - Two muscle tissues that run along the shoulder blade form the edges of the bulge. One edge runs transversely on the front side, and the other is on the back side of the shoulder blade. - The main muscle running through this area is called the trapezius muscle. It is a long and thick muscle that runs from the base of the neck to the back. It is attached to the hanger, but mainly it
