Deltoid Region

The deltoid is the triangular area located between the back of the arm and the sternocleidomastoid muscle. The anatomy of this area includes superficial (located closer to the surface of the body) and deep (located further from the skin). Superficial include the deltoid muscles, and deep include fascia, vascular structures and nerves. At the medial border of the deltoid region are the posterior portion of the subclavian artery and vein. The subdeltoid nerve is located in the lower half of the lateral border. The deltoid region is often injured during injuries to the shoulder or forearm bones. Such injuries can lead to disability and a decrease in the quality of life of victims.

Before considering the structure of the deltoid muscles, you need to understand that this group connects three main parts of the body to each other: hand, elbow, shoulder. It also connects the forelimb to the human arms, creating conditions for active work of the whole body. When considering the anatomy of the deltoid muscles, we will definitely consider the shoulder joint, which connects three bones (humerus, ulna, radius). The deltoid muscles differ in function, placement and tone of the fibers in them.

The transverse muscular plane is located on the posterior surface of the deltoid
