Anatomical terms of bone
[edit on Wikidata]
In anatomy, a sesamoid bone (/ˈsɛsəmɔɪd/)[1][2] is a bone embedded within a tendon or a muscle.[3] Its name is derived from the Greek word for 'sesame seed', indicating the small size of most sesamoids. Often, these bones form in response to strain,[4] or can be present as a normal variant. The patella is the largest sesamoid bone in the body. Sesamoids act like pulleys, providing a smooth surface for tendons to slide over, increasing the tendon's ability to transmit muscular forces.[3]
