Musculature

“The Rotator Cuff”

Muscle Actions Deltoid  Abducts the Shoulder Supraspinatus  Leads to the first 10 – 15 degrees of Abduction Infraspinatus  Hold the head of the Humerus in the Glenoid Cavity Teres Minor  Hold the head of the Humerus in the Glenoid Cavity Subscapularis  Internal Rotation/Draws the Humerus Forward & Downward

Nerve innervation of the shoulder Cranial nerves into the Brachial Plexus:
