[10m] Name this compartment, bounded on one side by the flexor retinaculum (reh-tin-ACK-you-lum) and on the other side by the hamate, capitate, trapezium, and trapezoid. Its contents include several muscle tendons and the median nerve.
ANSWER: carpal tunnel [or the carpal canal]

ANSWER: ulna
[10h] This other space on the back of the hand near the base of the thumb is bounded by the tendons of extensor pollicis longus and extensor pollicis brevis. Scaphoid fractures cause tenderness in this space, whose name references its usefulness in holding tobacco or cocaine.
