Watch out for the common problem of mistaking the tendons long and short heads of the biceps brachii due to the overlying deltoid. Know the attachments of these tendons and note how the muscles have 2 actions because they cross 2 joint. Know all 3 muscles that attach to the coracoid process 1) pectoralis minor, 2) short head of biceps and 3) coracobrachialis. Note the musculocutaneous (branch of the lateral cord) passes though the coracobrachialis to innervate the anterior compartment of the arm.
