The twins constitute with soleus muscles the gastrocnemius. They form the curve of the calf. They are two: the internal twin and the external twin.

They cover the soleus muscle and are located on the rear part of the leg. The leg is the part of the body between the knee and the ankle. Twins are attached to the tibia at its lower part and end on Achilles tendon that fixes on the calcaneus (bone of the foot). Twins take part in the bending of the knee.
