The calf muscles are located at the back of the lower leg and consist primarily of two main muscles: the gastrocnemius and the soleus. The gastrocnemius is the larger muscle, giving the calf its prominent shape, while the soleus lies underneath it. Together, these muscles play a crucial role in movements such as walking, running, and jumping by helping to lift the heel off the ground. These muscles are also important for maintaining balance and stability during various activities. They work together to control the movement of the ankle joint, allowing for smooth transitions between different positions, such as standing on tiptoes or pushing off the ground while moving.
