Question

Which is a sesamoid bone?
A)Patella
B)Cuboid
C)Talus
D)Sphenoid
E)Scaphoid

Accepted Answer

The patella, also known as the kneecap, is a sesamoid bone located in the front of the knee joint. Sesamoid bones are unique in that they develop within a tendon or muscle and function to protect the tendon or alter the angle of insertion. The patella functions to improve the mechanical advantage of the quadriceps muscle by increasing the lever arm of the knee joint during extension.
