Flexor Region of the Forearm - True/False
1. Muscles that arise from the common flexor tendon are innervated by the median, ulnar, and musculocutaneous nerves.
2. Brachioradialis, a muscle of the posterior compartment of the forearm flexes the wrist and extends the fingers.
3. Flexor carpi radialis passes through the carpal tunnel and inserts onto the trapezium.
4. Palmaris longus inserts onto the palmar aponeurosis and palmaris brevis insert onto the palmar skin.
5. The median nerve enters the carpal tunnel lateral to palmaris longus and medial to flexor carpi radialis.
6. The radial side of the flexor digitorum superficialis is innervated by the radial nerve and the ulnar side is innervated by the ulnar nerve.
7. Flexor digitorum superficialis has two heads of origin; one from the lateral humeral epicondyle and one from the medial humeral epicondyle.
8. Between the heads of origin of flexor digitorum superficialis is a tendinous arch having a free edge that provides passage into the deep part of the anterior compartment.
9. The ulnar nerve enters the forearm by passing between the humeral and ulnar heads of pronator teres.
10. The ulnar half of the flexor digitorum profundus is innervated by the median nerve and the radial half is innervated by the radial nerve.
11. The most distal motor innervation of the anterior interosseous nerve is flexor pollicis longus.
12. The anterior interosseous nerve passes posterior to pronator quadratus and extends distally to provide sensory innervation to the carpal bones and joints.
13. The anterior interosseous artery passes posterior to proximal edge of pronator quadratus and then passes through the interosseous membrane to arrive in the posterior forearm.
14. The anterior interosseous artery supplies the dorsal carpal rete along with the dorsal carpal branch of the radial artery.
15. A total of 8 tendons from the anterior forearm enter the carpal tunnel.
16. The tendon of flexor pollicis longus passes through a partition of the flexor retinaculum separate from the carpal tunnel.
17. The posterior interosseous artery leaves the anterior compartment to enter the posterior compartment by passing superior to the free edge of the interosseous membrane and inferior to the oblique.
18. The interosseous recurrent artery passes ascends toward the lateral epicondyle by passing through anconeus.
19. Flexor pollicis longus takes origin from the common flexor tendon and the radius.
20. The lateral half of the flexor digitorum profundus is one of three muscles innervated by the anterior interosseous nerve.
