The gastrocnemius muscle is also called the two-headed calf muscle or twin muscle. Functionally, this muscle works together with the soleus muscle. Therefore, these two muscles are combined to form the triceps surae muscle. The gastrocnemius muscle has two muscle heads. The caput mediale originates at the epicondylus medialis femori, whereas the caput laterale originates at the epicondylus lateralis femoris. The two muscle heads meet at an acute angle. This creates a caudal boundary of the popliteal fossa. In about one-third of all cases, a sesamoid bone, the fabella, is expressed in the caput laterale. The broad terminal tendon arises from the junction of the two muscle bellies. This tendon fuses with the end tendon of the soleus muscle to form the Achilles tendon and attaches to the tuber calcanei of the calcaneus.
