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).
In both of these locations, the tendon is thickened. At the cuboid, a fibrocartilaginous sesamoid (sometimes a sesamoid bone) usually develops in the substance of the tendon. [2] The fibularis longus muscle is supplied by the superficial fibular nerve, which arises from the fifth lumbar and first sacral roots of the spinal cord. [3]
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.
However, sesamoid bones (likely what you're calling tendon bones) are more like pulleys for the tendons, in essence modifying the direction of the force the muscle applies to the bone to which is ...

the fibular region encompassing the outside of the lower leg, the tarsal region encompassing the ankle, the pedal region encompassing the foot; the digital/phalangeal region encompassing the toes. The great toe is referred to as the hallux. The regions of the upper limbs, from superior to inferior, are the axillary region encompassing the armpit,
Structures found in the posterolateral corner include the tibia, fibula, lateral femur, iliotibial band (IT band), the long and short heads of the biceps femoris tendon, the fibular (lateral) collateral ligament (FCL), the popliteus tendon, the popliteofibular ligament, the lateral gastrocnemius tendon, and the fabellofibular ligament.
