Carpal tunnel
Carpal Tunnel
Carpal Tunnel (pronunciation: /ˈkɑːr.pəl ˈtʌn.əl/) is a narrow passageway located on the palm side of the wrist. This tunnel protects the main nerve to the hand and the nine tendons that bend the fingers.
Etymology
The term "Carpal" is derived from the Greek word karpos which means "wrist". The word "Tunnel" refers to the tunnel-like structure formed by the carpal bones and the transverse carpal ligament.
Anatomy
The Carpal Tunnel is bounded by the carpal bones on the dorsal side and the Transverse Carpal Ligament on the palmar side. It houses the Median Nerve and the tendons of the Flexor Digitorum Superficialis and Flexor Digitorum Profundus muscles.
Carpal Tunnel Syndrome
Carpal Tunnel Syndrome is a common condition that causes pain, numbness, and tingling in the hand and arm. It occurs when the Median Nerve, which runs from the forearm into the palm of the hand, becomes pressed or squeezed at the wrist.
