Gastrocnemius. 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.
The gastrocnemius is one of the calf muscles, but attaches to the femur at the back of the knee, and runs down to attach to the calcaneus (heel bone) through the achilles tendon. It acts as a secondary knee flexor.his tendon continues below the patella to connect to the tibia. These muscles extend, or straighten, the knee. The hamstrings are the muscles on the back of the thigh. This muscle group is composed of the biceps femoris (outside), the semimembranosus, and the semitendinosus (inside).
