Which structures are contained within the carpal tunnel?

• A. Extensor tendons and Ulnar nerve
• B. Flexor digitorum profundus and Ulnar nerve
• C. Flexor digitorum superficialis and Median nerve
• D. Flexor tendons and Median nerve

Answer: (D)

The carpal tunnel is a narrow passageway located on the palm side of the wrist that plays a crucial role in the passage of certain structures. It is primarily composed of the flexor retinaculum and the carpal bones. Within this tunnel, the structures that pass through include the flexor tendons and the median nerve. The flexor tendons encompass the tendons of the flexor digitorum profundus and flexor digitorum superficialis, which are responsible for flexing the fingers. The median nerve provides motor and sensory innervation to parts of the hand, particularly the thumb, index, middle, and part of the ring finger. This arrangement is essential as it plays a significant role in the function of the hand, and any compression of the structures within the tunnel, especially the median nerve, can lead to conditions such as carpal tunnel syndrome. Thus, the passing of flexor tendons and the median nerve through the carpal tunnel is vital for hand movement and sensation, making this answer correct. The other choices do not include all the correct structures that are anatomically located within the carpal tunnel.
