gastrocnemius - the muscle in the back part of the leg that forms the greater part of the calf; responsible for the plantar flexion of the foot gastrocnemius muscle skeletal muscle, striated muscle - a muscle that is connected at either or both ends to a bone and so move parts of the skeleton; a muscle that is characterized by transverse stripes
The gastrocnemius muscle is a muscle located on the back portion of the lower leg, being one of the two major muscles that make up the calf.The other major calf muscle, the soleus muscle, is a flat muscle that lies underneath the gastrocnemius.oth the gastrocnemius and the soleus run the entire length of the lower leg, connecting behind the knee and at the heel. A third muscle, the plantaris muscle, extends two-to-four inches down from the knee and lies between the gastrocnemius and the soleus.
