Animation of shoulder joint showing the supraspinatus muscle. The rotator cuff muscles of the shoulder produce a high tensile force, and help to pull the head of the humerus into the glenoid cavity. The glenoid cavity is shallow and contains the glenoid labrum which deepens it and aids stability. With 120 degrees of unassisted flexion, the ...
Shoulder anatomy, front view Shoulder anatomy, back view. The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. [3] These muscles are the supraspinatus, infraspinatus, teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during ...
These muscles arise from the scapula and connect to the head of the humerus, forming a cuff at the shoulder joint (hence the name rotator cuff). They hold the head of the humerus in the small and shallow glenoid fossa of the scapula. The glenohumeral joint has been analogously described as a golf ball (head of the humerus) sitting on a golf tee ...
Name Explanation Muscle US English [a] name of the muscle per Terminologia Anatomica (TA), [13] minus the term "muscle", with the words reordered occasionally for better sorting. Parts and bellies are listed out as separate rows, as they are sometimes considered separate muscles.

The capsule of the glenohumeral (shoulder) joint is the articular capsule of the shoulder.It completely surrounds the joint. It is attached above to the circumference of the glenoid cavity beyond the glenoidal labrum, and below to the anatomical neck of the humerus, approaching nearer to the articular cartilage above than in the rest of its extent.
The glenohumeral joint (colloquially called the shoulder joint) is the highly mobile ball and socket joint between the glenoid cavity of the scapula and the head of the humerus. Lacking the passive stabilisation offered by ligaments in other joints, the glenohumeral joint is actively stabilised by the rotator cuff , a group of short muscles ...
In human anatomy, the glenohumeral ligaments (GHL) are three ligaments on the anterior side of the glenohumeral joint (i.e. between the glenoid cavity of the scapula and the head of the humerus; colloquially called the shoulder joint).
