Eg. Patella and navicular bone. Found within tendons, where they change direction over prominences that would otherwise cause damage. They form '''synovial joints''' with major bones with which they are in contact. They also serve to displace tendon from the axis of the joint, increasing the leverage exerted by the muscle. | Eg.
