Space between the carpal bone and the accessory carpal bone is called the carpal canal.

• A. Carpal canal
• B. Carpal tunnel
• C. Carpal space
• D. Carpal arch

Answer: (A)

That space is called the carpal canal. It forms a passage that houses the flexor tendons as they pass from the forelimb to the digits and is bounded dorsally by the carpal bones and palmarly by the flexor retinaculum. In veterinary anatomy this term is used for the space between the carpal bones and the accessory carpal bone. The term carpal tunnel is commonly used in human anatomy to describe a passage under the flexor retinaculum that contains the median nerve and flexor tendons, but in animals the specific space between the carpal and accessory carpal bones is referred to as the carpal canal. The other terms—carpal space and carpal arch—do not denote this enclosed passage between those bones.
