As a ball and socket synovial joint, there is a wide range of movement permitted:

EXTENSION (upper limb backwards in sagittal plane) – posterior deltoid, latissimus dorsi and teres major.

FLEXION (upper limb forwards in sagittal plane) – pectoralis major, anterior deltoid and coracobrachialis. Biceps brachii weakly assists in forward flexion.

ABDUCTION (upper limb away from midline in coronal plane):
-The first 0-15 degrees of abduction is produced by the supraspinatus.
-The middle fibres of the deltoid are responsible for the next 15-90 degrees.
-Past 90 degrees, the scapula needs to be rotated to achieve abduction – that is carried out by the trapezius and serratus anterior.

ADDUCTION (upper limb towards midline in coronal plane) – pectoralis major, latissimus dorsi and teres major.

INTERNAL ROTATION (rotation towards the midline, so that the thumb is pointing medially) – subscapularis, pectoralis major, latissimus dorsi, teres major and anterior deltoid.

EXTERNAL ROTATION (rotation away from the midline, so that the thumb is pointing laterally) – infraspinatus and teres minor.

CIRCUMDUCTION (moving the upper limb in a circle) – produced by a combination of the movements described above.
