The |soleus| is a thick muscle located on the back of the lower leg. It originates from the upper part of the |fibula| (lower leg bone) and the tendonous arch connecting the head of the |fibula| to the |tibia|. The muscle is thickest at its mid-section where its flattened form curves around the deep flexor muscles of the foot and toes. The muscle tapers low, just above the ankle, and its ~tendon~ continues on inserting in the middle part of the calcaneum (heel bone). This muscle is used to point the foot or raise the heel, which lifts the body. Its continuous |contraction| of the |soleus| prevents the body from falling forward when standing.
