The carpals are the bones you feel when you touch your wrist. In the wrist is the carpal tunnel, which is enclosed by the carpals on three sides, and on the fourth side, by a transverse carpal ligament. Within this narrow space, is not only the median nerve, but also nine flexor tendons. These tendons help you bend your wrist. As you can imagine, it’s a pretty tight squeeze. If for some reason the carpal tunnel is too small, or if the tendons within the tunnel become larger, your median nerve will be compressed.
