Figure 10-2. The superficial palmar arch (see also fig. 11-10), the flexor retinaculum, and the structures on the front of the wrist (see also fig. 10-5). The palmar aponeurosis has been removed. Note the median nerve passing deep to the flexor retinaculum (within the carpal tunnel) and, immediately on emerging, giving off its very important recurrent branch to the thenar muscles.
