Document Summary

Minor, subscapularis: deltoid, trapezius, latissimus dorsi, teres major, all of these muscles are innervated by the brachial plexus. Pectoralis major muscle: origin is on the clavicle and the sternum, upper fibers are flexion and lower fibers are extension. Latissimus dorsi: broadest muscle of the back , origin: vertebrae down to the sacrum. Insertion: intertubercular groove: action: adduction, extension, internal rotation, horizontal abduction, exercises: swimming, lat pull down, rowing, pull ups. Teres major: known as the lats little helper : origin: inferior angle of the scapula. Insertion: intertubercular groove: action: extension, adduction, internal rotation, exercises: rowing, pull ups. Coracobrachialis muscle: origin: coracoid process of the scapula. Insertion: the humerus: action: horizontal adduction, flexion, adduction. Rotator cuff muscles: provide stability to the shoulder: sits: supraspinatus, infraspinatus, teres minor, subscapularis, origin. 2: tendinitis is a common problem with these muscles. Impingement: when the tendons of the muscles become inflamed, there"s a lot of tendons that run through there.
