Century Dictionary and Cyclopedia
    • n gastrocnemius A superficial muscle of the posterior tibial region, arising from the femur and inserted into the tarsus, the action of which extends the foot upon the leg, and flexes the leg upon the thigh: so called from its character in man, in whom it forms, together with the soleus, the protuberant or “bellying” part of the calf of the leg. In man the gastrocnemius arises by two heads, inner and outer, from the corresponding condyles of the femur, is joined by the soleus, and then forms a very stout tendon, the tendo Achillis, which is inserted into the tuberosity of the os calcis or heel-bone. (See cut under muscle.) In animals in which there is no soleus the two heads of the gastrocnemius often form two muscles, distinct in their whole length, with separate Achillean tendons.

In news:

The outer calf muscle, the gastrocnemius, runs from above the knee to the ankle, and when it's too tight, it can throw off everything from the thigh to the foot.
A calf pull (also called a strain or tear) occurs when one of the calf muscles (gastrocnemius or soleus) is stretched beyond its limits and separates from the Achilles tendon.
The Achilles tendon is a continuum of coalescence between the two heads of the gastrocnemius and the soleus muscles.
