In anatomy, a sesamoid bone (/ËsÉsÉmÉÉªd/) is a bone embedded within a tendon or a muscle. It is derived from the Latin word sesamum (sesame seed), due to the small size of most sesamoids. Often, these bones form in response to strain. In the hand â two sesamoid bones are commonly found in the distal portions of the first metacarpal bone (within the tendons of adductor pollicis and flexor pollicis brevis).
