Comments:
: Arm and Cubital Fossa: Learning Objectives and Review Questions : True/false : 1. The pectoralis major crosses the transverse humeral ligament prior to inserting on the lateral lip of the intertubercular sulcus (bicipital groove). : 2. The brachialis acts only at the elbow. It is a monoarticular muscle. : 3. The radial collateral artery, within the cubital fossa, is between the ulnar head of pronator teres and the medial border of the brachialis. : 4. The radial collateral artery travels through the medial head of the triceps and forms an anastomosis with the interosseus recurrent artery. : 5. The posterior ulnar recurrent artery passes between the heads of origin of the flexor carpi ulnaris. : 6. The brachial artery crosses the median nerve on the anterior side of the median nerve. (hint: what is the relation of the medial cord to the axillary artery) : 7. Within the cubital fossa the median nerve lies medial to the brachial artery. : 8. The median cubital vein crosses the posterior (deep) surface of the bicipital aponeurosis. : 9. Generally, it is within the cubital fossa that the radial artery terminates into superficial and deep branches. : 10. The radial recurrent artery is, in part, within the cubital fossa. : 11. The ulnar head of the pronator teres takes origin from the coronoid process. : 12. The biceps tendon inserts on the tuberosity of the ulna. : 13. The brachialis inserts on the radial tuberosity. : 14. Fexion and supination at the elbow are syngergistic actions of the biceps. : 15. The superior ulnar collateral artery passes posterior the medial epicondyle of the humerus. : 16. The musculocutaneous nerve pierces the short head of the biceps upon entering the arm. : 17. The lateral antebrachial cutaneous nerve can be found in the cubital fossa. : 18. The radial nerve passes posterior to the superior free edge of the teres major to enter into the triangular interval. : 19. The inferior ulnar collateral artery converges with the unlar nerve at the anterior region of the lateral humeral epicondyle. : 20. The coracobrachialis and the short head of the biceps are both biarticulate and have a common site of origin. : Essay : 1. Discuss the posterior compartment of the arm. Include contents, compartments, relationships, boundaries, fascial specializations, vascularization, innervation, lymphatics, muscles and movements, and compensation in the case of nerve injury. : 2.

Discuss the long head of the biceps muscle. Include fascial specializations, relationships, vascularization, innervation, lymphatics, movements, and compensation in the case of nerve injury. : 5. Discuss the long head of the triceps muscle. Include fascial specializations, relationships, vascularization, innervation, lymphatics, movements, and compensation in the case of nerve injury. : 6. Discuss the lateral head of the triceps muscle. Include fascial specializations, relationships, vascularization, innervation, lymphatics, movements, and compensation in the case of nerve injury. : 7. Discuss the medial head of the triceps muscle. Include fascial specializations, relationships, vascularization, innervation, lymphatics, movements, and compensation in the case of nerve injury. : 8. Discuss the brachialis muscle. Include fascial specializations, relationships, vascularization, innervation, lymphatics, movements, and compensation in the case of nerve injury. : 9. Discuss the anconeus muscle. Include fascial specializations, relationships, vascularization, innervation, lymphatics, movements, and compensation in the case of nerve injury. : 10. Discuss the brachioradialis muscle. Include fascial specializations, relationships, vascularization, innervation, lymphatics, movements, and compensation in the case of nerve injury. : 11. Discuss the pronator teres muscle. Include fascial specializations, relationships, vascularization, innervation, lymphatics, movements, and compensation in the case of nerve injury. : 12. Discuss the supinator muscle. Include fascial specializations, relationships, vascularization, innervation, lymphatics, movements, and compensation in the case of nerve injury. : 13. Discuss the brachial artery and its branches. Include relationships, fascial specializations, and collateral circulation. : 14. Discuss the profunda brachii artery and its branches. Include relationships, fascial specializations, and collateral circulation. : 15. Discuss the musculocutaneous nerve in the arm. Include relationships, fascial specializations, movements, and compensation for nerve injury. : 16. Discuss the radial nerve in the arm. Include relationships, fascial specializations, movements, and compensation for nerve injury. : 17. Discuss the ulnar nerve in the arm. Include relationships, fascial specializations, movements, and compensation for nerve injury. : 18. Discuss the median nerve in the arm.
