: : Arm and Cubital Fossa - True/False

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