    Study Notes

    Deltoid Muscle

    • Anterior fibers originate from the anterior border of the lateral 1/3 of the clavicle
    • Middle fibers originate from the lateral border of the acromion
    • Posterior fibers originate from the lower lip of the spine of the scapula
    • Inserts into the deltoid tuberosity of the humerus
    • Innervated by the axillary nerve (C5&6)

    Subscapularis Muscle

    • Occupies the medial 3/4 of the subscapular fossa
    • Inserts into the lesser tuberosity
    • Innervated by the subscapular nerves (C5&6)

    Supraspinatous Muscle

    • Occupies the medial 3/4 of the supraspinatous fossa
    • Inserts into the top of the greater tuberosity (double)
    • Innervated by the suprascapular nerve (C5&6)

    Infraspinatous Muscle

    • Occupies the medial 3/4 of the infraspinatous fossa
    • Inserts into the middle impression of the greater tuberosity
    • Innervated by the suprascapular nerve (C5&6)

    Rotator Cuff

    • Consists of Supraspinatus, Infraspinatus, Subscapularis, Teres major, and Teres minor muscles

    Teres Minor Muscle

    • Occupies the upper 2/3 of the dorsal aspect of the lateral border of the scapula
    • Inserts into the lower impression of the greater tuberosity
    • Innervated by the axillary nerve (C5&6)
