the tuberosity of the tibia. On the posterior surface there are 

 three sesamoid bones, of which one (in the medial head of the 

 gastrocnemius) lies in association with the medial condyle of the 

 femur, while the remaining two are associated respectively with 

 the lateral condyle of the femur (imbedded in the lateral head of 

 the gastrocnemius and the plantaris) and that of the tibia (con- 

 tained in the popliteus muscle). The sesamoids of the foot are 

 situated at the metatarso-phalangeal joints and at those connecting 

 the second and third phalanges.
