Sesamoid bones can be found on joints throughout the human body, including: In the knee—the patella (within the quadriceps tendon). This is the largest sesamoid bone. [4] 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).
Skeleton of the lower forelimb. Each forelimb of the horse runs from the scapula or shoulder blade to the third phalanx (coffin or pedal) bones. In between are the humerus (arm), radius (forearm), elbow joint, ulna (elbow), carpus (knee) bones and joint, large metacarpal (cannon), small metacarpal (splint), sesamoid, fetlock joint, first phalanx (long pastern), pastern joint, second phalanx ...
The distal sesamoidean ligaments run from the sesamoid bones to the two pastern bones. Biceps brachii: originates from the caudal side of the scapula and inserts into the radial tuberosity. Flexes the elbow, and is the part of the stay apparatus that keeps the elbow and shoulder from bending. [7]
Inter-sesamoidean ligament: supporting ligament cconnecting the two sesamoid bones. Distal sesamoidean ligaments: run from the sesamoid bones to the two pastern bones. Important in the stay apparatus as a functional continuation of the suspensory ligament. Impar ligament: runs between the navicular bone and the 3rd phalanx.

A sesamoid bone is a small, round bone that, as the name suggests, is shaped like a sesame seed. These bones form in tendons (the sheaths of tissue that connect bones to muscles) where a great deal of pressure is generated in a joint. The sesamoid bones protect tendons by helping them overcome compressive forces.
Some reliable sesamoid bones such as the pisiform are counted, while others, such as the hallux sesamoids, are not. Individuals may have more or fewer bones than the average (even accounting for developmental stage) owing to anatomical variations.
