Pea bone
The round Pisiform ( lat. Pisiform , even accessory carpal bone of "additional carpal bones") is the smallest of the eight carpal bones of vertebrates and the proximal part ( proximal ) series of short bones to.
It is located at the side ( lateral ) and away from the body ( distal ) of the ulna ( ulna ). At the end of the little finger ball that is close to the body , the pea bone can be easily felt from the outside through the skin and during the rotational movements of the forearm ( pronation and supination ) it can be found on the triangular bone ( os triquetrum ), with which it forms an articulated connection on the back of the hand ( dorsal ) , to move back and fourth. The pea bone is embedded in the tendon of the flexor carpi ulnaris muscle and is one of the so-called sesamoid bones .
