Lateral clavicle (anterior fibers) 2. Acromion (lateral fibers) 3. Spine of scapula (posterior fibers) Ins: Deltoid tuberosity of humerus Fun: N: Axillary Subscapularis: Ori: Subscapular fossa Ins: Lesser tubercle of humerus Fun: N: Upper and lower subscapularis  Supraspinatus: Ori: Supraspinous fossa Ins: Greater tubercle of humerus Fun: N: Suprascapular  Infraspinatus: Ori: Infraspinous fossa Ins: Greater tubercle of humerus Fun: N: Suprascapular  Teres Minor: Ori: The superior lateral border of scapula Ins: Greater tubercle of humerus Fun: N: Axillary  Teres Major; Ori: The inferior lateral border of scapula Ins: Medial lip of intertubercular (bicipital) sulcus (groove) of humerus Fun: N: Upper & lower subscapular Rotator Cuff Muscles Includes 4 Muscles: Supraspinatus Infraspinatus Teres Minor Subscapularis  They strengthen the shoulder joint capsule all around except inferiorly. This explains why dislocations of the humerus occur most commonly in a downward direction. Axillary Spaces  Axillary N.  Posterior femoral circumflex A. Circumflex scapular A.  Radial N.  Profunda brachii A.
