: : 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.
: False, just median and ulnar - Agree.
: : 2. Brachioradialis, a muscle of the posterior compartment of the forearm flexes the wrist and extends the fingers.
: False, flex wrist, pronate from supinated position, supinate from pronated positions - Agree. But..... Does not flex wrist!!!!! Or extend fingers.
: : 3. Flexor carpi radialis passes through the carpal tunnel and inserts onto the trapezium.
: False, does not pass through CT - Agree.
: : 4. Palmaris longus inserts onto the palmar aponeurosis and palmaris brevis insert onto the palmar skin.
: True - Agree.
: : 5. The median nerve enters the carpal tunnel lateral to palmaris longus and medial to flexor carpi radials.
: False, neither PL nor FLR are in carpal tunnel. Diagree. This is the relationship as median n. enters the carpal tunnel.
: : 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.
: False, median - Agree.
: : 7. Flexor digitorum superficialis has two heads of origin; one from the lateral humeral epicondyle and one from the medial humeral epicondyle.
: False, humoral and ulnar heads - Agree.
: : 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.
: True - Agree.
: : 9. The ulnar nerve enters the forearm by passing between the humeral and ulnar heads of pronator teres.
: False, flexor carpi ulnaris? - Agree.
: : 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.
: False, ulnar n and anterior interosseous(Median) - Agree.
: : 11. The most distal motor innervation of the anterior interosseous nerve is flexor pollicis longus.
: Flexor policis longus tendon runs further however pronator quadratus' muscle belly is more distal than FPL. I could see this going either way - Agree. Branching. PQ.
: : 12. The anterior interosseous nerve passes posterior to pronator quadratus and extends distally to provide sensory innervation to the carpal bones and joints.
: False, no sensory innervation, anterior - Disagree. Notice that I did not write "cutaneous."
: : 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.
: True - Agree.
: : 14. The anterior interosseous artery supplies the dorsal carpal rete along with the dorsal carpal branch of the radial artery.
: True - Agree.
: : 15. A total of 8 tendons from the anterior forearm enter the carpal tunnel.
: False, 9. - Agree.
: : 16. The tendon of flexor pollicis longus passes through a partition of the flexor retinaculum separate from the carpal tunnel.
: False - Agree.
: : 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.
: True - Agree. Oblique cord.
: : 18. The interosseous recurrent artery passes ascends toward the lateral epicondyle by passing through anconeus.
: false, supinator? - Disagree. Anconeus.
: : 19. Flexor pollicis longus takes origin from the common flexor tendon and the radius.
: False, not from CFT - Agree.
: : 20. The lateral half of the flexor digitorum profundus is one of three muscles innervated by the anterior interosseous nerve.
: True - Agree.
