6. The following structures lie within the carpal
tunnel
1 ulnar nerve
2 ulnar artery
3 Palmaris longus tendon
4 Flexor pollicis longus tendon
5 Pronator quadratus

7. The carpal tunnel is the space that lies between the flexor retinaculum (transverse
carpal ligament) and the ventral surface of the articulated carpus.
The ulnar nerve, ulnar artery and the tendon of palmaris longus run superficial to
the flexor retinaculum and thus are not within the carpal tunnel.
Flexor pollicis longus enters the carpal tunnel before reaching its insertion on the
distal phalanx of the thumb.
Pronator quadratus is confined to the distal forearm and does not reach the carpal
tunnel.

4 Flexor pollicis longus tendon T
5 Pronator quadratus F

closed fist, and is due to paralysis of adductor pollicis which is supplied by the ulnar
nerve.
The ulnar side of the dorsum of the hand is innervated by the dorsal branches of the
ulnar nerve but these are given off several cms proximal to the flexor retinaculum

the dorsum of hand

14. Extensor expansions of the fingers (dorsal digital expansions):
1 are enclosed in synovial sheaths
2 receive the insertions of the dorsal interossei
