Shoulder Muscles Sports Medicine I

Shoulder Movements Flexion Extension Abduction Adduction Horizontal Abduction Internal Rotation (0 and 90) External Rotation (0 and 90)

Shoulder Movements Circumduction Elevation Depression Protraction Retraction

Biceps Flexion Supination

Coracobrachialis Adduction Assists flexion and pronation

Deltoid Anterior Fibers Middle Fibers Posterior Fibers Flexion, horizontal adduction, internal rotation, external rotation

Infraspinatus External rotation (rotator cuff)

Lattisimus Dorsi Extends arm

Levator Scapulae Elevates scapula

Pectoralis Major Flexes upper arm Adducts arm

Pectoralis Minor Raises ribs for inspiration

Rhomboids Retraction and rotation of scapula

Serratus Anterior Rotates scapula for abduction

Subscapularis Internal rotation (rotator cuff)

Teres Major Assists in extension

Teres Minor External rotation (rotator cuff)

Trapezius Retraction Upward rotation Elevates scapula

Triceps Extends forearm and upper arm
