Document Summary

Muscles of the pectoral girdle and upper limbs. Muscles of the pectoral girdle/shoulder girdle: are separated into 2 groups, muscles that move the shoulder. Anterior: posterior, muscles that move the humerus, axial. Pectoral girdle: muscles that move the shoulder: posterior (large muscles, trapezius. Middle bres (adduct- bring it towards the midline) hint: how is the glenoid fossa moving: rhomboids + innervation to the muscle is the dorsal scapula. nerve elevate, adduct and downward rotation. Minor smaller of the two: levator scapulae innervation to the muscle is the dorsal scapula. nerve elevate and downwardly rotates scapula, anterior, muscles: pectoralis minor attaches from the coracoid process of scapula to ribs. Pectoral girdle: muscles that move the humerus: anterior = pectoralis major: pectoral nerve, posterior = latissimus dorsi: thoracodorsal nerve axial, pectoralis major (anterior) originates off the sternum and borrows part of a clavicle.
