Human Anatomy
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).
- 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). In some people, only a single sesamoid is found on the first MTP.

Famous quotes containing the words human and/or anatomy:
“It is no small mischief to a boy, that many of the best years of his life should be devoted to the learning of what can never be of any real use to any human being. His mind is necessarily rendered frivolous and superficial by the long habit of attaching importance to words instead of things; to sound instead of sense.”
—William Cobbett (1762–1835)
“Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world.”
—Ralph Waldo Emerson (1803–1882)
