Document Summary

Superficial layer: trapezius, latissimus dorsi, teres major, deltoid, rhomboid major, rhomboid minor, levator scapula, supraspinatus. Infraspinatus: teres minor, serratus anterior, triceps brachii, lateral head, long head, medial head. Anterior thoracic wall: pectoralis major, pectoralis minor, deltoid, trapezius, latissimus dorsi, biceps brachii, short head, long head, pectoral fascia, clavipectoral fascia, clavipectoral/deltopectoral triangle, borders: Medial border of scapula at root of scapula: pa, da, n: dorsal scapular nerve (c4, c5, a: retract scapula (pull vertebral border closer to sp) Superior angle of scapula: pa, da, n: dorsal scapular nerve (c4, c5, a: elevate scapula (grabs superior angle and pulls it up, downward rotation of scapula. As you elevate the scapula, the glenoid fossa points downward. Costal (anterior) surface of scapula: pa, da, wraps around ribcage and runs between ribcage and scapula before it attaches onto anterior border, n: long thoracic nerve (c5-c7, sits on superficial surface of sa. Vulnerable nerve: only thing protecting it is subcutaneous tissue and skin.
