Arm and Cubital Fossa - True/False

1. The median nerve is medial to the brachial artery at the level of the cubital fossa.
2. The brachial artery, but not the median nerve, is protected by the bicipital aponeurosis.
3. The radial recurrent artery forms an anastomosis with the middle collateral artery.
4. The posterior ulnar recurrent artery forms an anastomosis with the inferior ulnar collateral artery.
5. The superior ulnar collateral artery and the posterior ulnar recurrent arteries supply the ulnar nerve within the cubital tunnel.
6. The olecranon process rests in the olecranon fossa when the elbow is flexed.
7. The coronoid process of the ulna rests in the radial fossa when the elbow is extended.
8. The terminal branch of musculocutaneous nerve passes to the lateral side of the biceps tendon and continues as the lateral antebrachial cutaneous nerve.
9. The median cubital vein passes superficial to the bicipital aponeurosis.
10. The basilic vein passes through the brachial fascia to join with the brachial veins and form the axillary vein.
11. The radial collateral artery passes through the lateral intermuscular septum with the radial nerve to enter the anterior compartment of the arm.
12. The middle collateral artery passes within the medial head of the triceps toward the posterior side of the lateral humeral epicondyle.
12. The ulnar nerve is accompanied by the ulnar artery as the two enter the cubital tunnel.
13. The musculocutaneous nerve is deep to biceps and superficial to brachialis.
14. The median nerve leaves the cubital fossa by passing between the heads of origin of the pronator teres.
15. The brachial artery passes deep to both heads of pronator teres.
16. The pronator teres passes superficial to brachioradialis at the apex of the cubital fossa.
17. Brachialis and the supinator contribute to the posterior boundary (floor) of the cubital fossa.
18. The radial nerve gives off the branch to brachioradialis within the cubital fossa.
19. The lateral head of the triceps is superior to the radial groove and the medial head of the triceps is inferior to the radial groove.
20. Each of the four terminal branches of the brachial plexus that enter the arm contribute to flexion at the elbow.
