APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The definitive shape of the calf is as a result of the medial and lateral heads of the gastrocnemius, which are situated at the posterior, upper half of the lower leg. With the soleus and plantaris, they form a composite muscle called the triceps surae.

Detailed explanation-2: -The gastrocnemius is the larger calf muscle, forming the bulge visible beneath the skin. The gastrocnemius has two parts or “heads, ‘’ which together create its diamond shape. The soleus is a smaller, flat muscle that lies underneath the gastrocnemius muscle.

Detailed explanation-3: -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.
