It runs from the back of the knee to the foot and gives sensation to the skin of the lateral foot and ankle. The lower leg refers to the portion of the lower extremity between the knee and ankle. This area consists of bones, muscles, tendons, and nerves that all work together to allow the leg to function.

The lower leg is divided into four compartments that contain the various muscles of the lower leg—anterior, lateral, posterior and deep posterior. The anterior compartment, in the front of the shin, holds the tibialis anterior, the extensor digitorum longus, the extensor hallucis longus, and the peroneus tertius muscles.
These muscles pull the toes and feet upward, a process known as dorsiflexion. The tibialis anterior also assists in turning the foot inward.
You can feel these muscles contract by placing your hand just to the outside of the tibia and pulling your foot up.
The lateral compartment is along the outside of the lower leg. It contains the peroneus longus and peroneus brevis muscles. These muscles pull the toes and feet outward. They also help with pointing the foot, or plantarflexion.
To feel these muscles contract, place your hand on the outside of your shin and turn your foot out. The posterior compartment holds the large muscles that we know as the calf muscles—the gastrocnemius and soleus. This compartment also contains plantaris muscle.
The gastrocnemius is shorter, thicker and has two inner and outer attachments. It is the most visible of the calf muscles. The soleus lies underneath.
These three muscles attach to the Achilles tendon, and they all aid with plantarflexion. The deep posterior compartment lies deep within the back of the lower leg. Next article Achilles tendinitis.
