What Are the Functions of the Calf Muscle?
The calf muscle, which runs from the back of the knee down to the ankle, is made up of one large muscle you can see (gastrocnemius), and a smaller muscle (soleus) under the gastrocnemius that is harder to pinpoint from the outside. A strong and healthy calf muscle is essential for a variety of functions, including obvious ones such as lifting the heel, and less obvious purposes, such as helping with circulation in the lower leg.
