Other Terms: Achilles tendon, Tendo calcaneus, Tendon calcanéen
The tendo calcaneus is the thickest tendon in the body. It begins near the middle of the calf as the compound tendon of the gastrocnemius and soleus muscles. It begins as a broad flat aponeurosis formed by the two bellies of the gastrocnemius, which is joined by the soleus as it descends in the leg. About four centimeters above the calcaneus it becomes thick and rounded before expanding again to insert into the tuber of the calcaneus.
