Capitate bone
Capitate Bone
The Capitate Bone (pronounced: /ˈkæpɪteɪt/ bone) is one of the eight carpal bones that are found in the human wrist. It is the largest of the carpal bones, and its name is derived from the Latin word 'caput', meaning 'head', due to its head-like shape.
Etymology
The term 'Capitate' is derived from the Latin word 'caput', which translates to 'head'. This is in reference to the bone's unique, head-like shape.
Anatomy
The Capitate Bone is situated in the center of the wrist, surrounded by the other seven carpal bones. It articulates with the third metacarpal bone directly and with the other metacarpal bones and carpal bones indirectly.
Function
The primary function of the Capitate Bone is to facilitate the movement of the wrist and hand. It plays a crucial role in the flexion, extension, and circumduction of the wrist.
