Main article

The median nerve passes through the carpal tunnel, a canal in the wrist that is surrounded by bone on three sides, and a fibrous sheath (the flexor retinaculum) on the fourth. In addition to the nerve, nine tendons — the flexor tendons of the hand—pass through this canal. The median nerve can be compressed by a decrease in the size of the canal or an increase in the size of the contents (such as the swelling of the lubrication tissue around the flexor tendons), or both. Simply bending the wrist at 90 degrees will decrease the size of the canal.
