Full Superficial Muscles of the Leg and Foot (Posterior View) Description

Placing one foot in front of the other is a process in which one constantly loses and regains balance as each step finds a new base. Synchronizing movements of the arms and legs, the muscles ensure that balance is restored before the body falls over.
Muscles and tendons anchor the joints at the pelvis, knee, and ankle together with the major bones of the leg and those of the foot. Many of these muscles are particularly large. This includes the hamstring muscles, and their tendon (hamstring), which flex and rotate the leg laterally and extend the thigh. Below that, the complex ligamentous system of the knee is the site of muscle attachment for some of the most powerful muscles in the body.
And below the knee, a number of muscles that function to move the ankle, foot, and toes are located in the lower leg. Included here are the muscles of the calf, which join the strong Achilles tendon, descend to the heel, and attach to the calcaneus. Altogether, they are responsible for a variety of movements of the foot and ankle, in addition to maintaining balance when the body is at rest.
