relatively narrow passageway that is formed anteriorly by the flexor retinaculum and posteriorly by the carpal bones. The median nerve which is the most superficial structure and the long flexor tendons for the digits (such as the flexor digitorum superficialis muscle and the flexor digitorum profundus muscle tendons) pass through this tunnel. Compression injury to the median nerve will result in a condition known as Carpal Tunnel Syndrome (CTS). The median nerve is responsible for transmitting sensory
