It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone.he Achilles tendon connects the gastrocnemius and soleus muscles to the calcaneus, the heel bone. The tendon begins near the middle of the calf, and receives fleshy fibers on its inner surface, almost to its lower end. Gradually thinning below, it inserts into the middle part of the back of the calcaneus bone.
