ANATOMY

Detailed explanation-1: -Your calf muscle consists of two main muscles-the gastrocnemius and the soleus. Because these two muscles come together above your heel and attach to the Achilles tendon, some providers refer to the gastrocnemius and soleus as one large muscle with two sections.

Detailed explanation-2: -The gastrocnemius muscle is superficial to (closer to the skin than) the soleus, which lies below the gastrocnemius. The plantaris muscle and a portion of its tendon run between the two muscles.

Detailed explanation-3: -The gastrocnemius is located with the soleus in the posterior compartment of leg. It is considered a superficial muscle as it is located directly under skin, and its shape may often be visualized through the skin. Deep to the gastrocnemius (farther from the skin) is the soleus muscle.

Detailed explanation-4: -gastrocnemius muscle, also called leg triceps, large posterior muscle of the calf of the leg. It originates at the back of the femur (thighbone) and patella (kneecap) and, joining the soleus (another muscle of the calf), is attached to the Achilles tendon at the heel.
