Wiki What's a sesamoid?

I am studying CPT's Surgery Musculoskeletal System, and I was wondering: What's a sesamoid as in sesamoidectomy under the Foot and Toes procedures? Thanks.

Sesamoid bones can be found on joints throughout the body, including:
In the knee ? the patella (within the quadriceps tendon).
In the hand ? 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). There is also commonly a sesamoid bone in distal portions of the second metacarpal bone.
In the wrist - The pisiform of the wrist is a sesamoid bone (within the tendon of flexor carpi ulnaris).[3]
In the foot - the first metatarsal bone usually has two sesamoid bones at its connection to the big toe (both within the tendon of flexor hallucis brevis).[4] In some people, only a single sesamoid is found on the first MTP.
