The rotator cuff muscles are perhaps the most important members of the muscles of the shoulder joint, and are essential to the healthy functioning of the glenohumeral joint. They are a set of four muscles that run from the scapula to the humerus. This group of muscles may also be referred to as the SITS muscles: the supraspinatus, infraspinatus, teres minor, and subscapularis.

Many other muscles act upon the glenohumeral joint. Here are some examples, arranged by order of their associated function:

Flexion - Pectoralis major, deltoid (Prime movers), Coracobrachialis, biceps brachii (Accessory muscles)

Extension- Deltoid (Prime mover), Teres major, latissimus dorsi , long head of biceps brachii (Accessory muscles)

Abduction- Deltoid (Prime mover), Supraspinatus (Accessory muscles)

Adduction- Pectoralis major, latissimius dorsi (Prime movers), Teres major, long head of triceps brachii (Accessory muscles)

Medial Rotation- Subscapularis (Prime mover), Pectoralis major, deltoid, latissimus dorsi, teres major (Accessory muscles)

Lateral Rotation- Infraspinatus (Prime mover), Teres major, deltoid (Accessory muscles)
