They are important in shoulder movements and maintaining stability of this joint.

Anatomy rotator cuff. Its function is related to the glenohumeral joint where the muscles of the cuff function both as the executors of the movements of the joint and the stabilization of the joint as well. This is the main muscle that lets you rotate and extend your shoulder. It is innervated by the upper and lower subscapular nerves.

Each one of these muscles is part of the rotator cuff and plays an important role. Together with the joint capsule ligaments and labrum the rotator cuff muscles are important dynamic stabilizers and movers of the shoulder joint. This holds your humerus in place and keeps your upper arm stable.

The most common signs of rotator cuff injuries are. The four muscles are the supraspinatus muscle the infraspinatus muscle teres minor muscle and the subscapularis muscle. Arthrogram a special type of x ray that uses dye injected into a joint to more clearly see detail in the tendons and muscles.

The rotator cuff is the most vulnerable part of the shoulder and is where most shoulder injuries occur. Pain may or may not be present. The rotator cuff is made up of four muscles whose tendons come together to form a covering around the head of the humerus upper arm bone and top of the shoulder.

Anatomy of rotator cuff the subscapularis arises from the anterior aspect of the scapula and attaches over much of the lesser tuberosity. The joint where the upper bone humerus of the arm meets the shoulder scapula and acromion process is called the rotator cuff. Of the seven scapulohumeral muscles four make up the rotator cuff.

Painful range of motion. They are important in shoulder movements and maintaining stability of this joint. Can be localized to anterior lateral aspect of the shoulder with referred pain down the upper arm lateral aspect.

In anatomy the rotator cuff is a group of muscles and their tendons that act to stabilize the shoulder and allow for its extensive range of motion. In the human body the rotator cuff is a functional anatomical unit located in the upper extremity.
