: 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.
True, median nerve passes deep to pronator teres
: 3. The radial recurrent artery forms an anastomosis with the middle collateral artery.
False, radial collateral
: 4. The posterior ulnar recurrent artery forms an anastomosis with the inferior ulnar collateral artery.
False, superior ulnar collateral
: 5. The superior ulnar collateral artery and the posterior ulnar recurrent arteries supply the ulnar nerve within the cubital tunnel.
False, anterior and posterior ulnar recurrents
: 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.
False, coronoid fossa
: 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.
False, recurrent radial a
: 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.
False, brachial a and median n
: 13. The musculocutaneous nerve is deep to biceps and superficial to brachial.
: 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.
False, branches into ulnar and radial artery before passing pronator teres
: 16. The pronator teres passes superficial to brachioradialis at the apex of the cubital fossa.
False, deep to
: 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.
False, just musculocutaneous and radial
