What nerve controls calf muscle?
The tibial nerve (S1, S2) innervates the majority of the muscles of the calf. The tibial nerve passes through the popliteal fossa and gives off branches to the gastrocnemius, popliteus, soleus, and plantaris muscles. There is also a cutaneous branch that will become the sural nerve.
Why is one calf more muscular than the other?
Dr. Anderson explains, “It may simply be due to the way a person stands, placing more weight on one leg over another. “It may also be that one side is being strengthened more than the other during exercise.” The fitness enthusiast may be unaware of this.
What exercise works the primarily the calf muscle?
Calf raises are the classic calf-strengthening exercise. They use your body weight to strengthen and tone the gastrocnemius and soleus. Starting position: Stand near a wall for balance.

What happens to the gastrocnemius muscle of your leg when the shank is flexed in walking?
The action in which your leg is bent back toward your backside is called knee flexion, and it occurs every time you walk. When you flex your knee, the gastrocnemius acts with the hamstrings, which are the muscles of the posterior upper leg, and the popliteus to bend it at the joint.
What is the function of soleus?
Soleus has two major functions: To act as skeletal muscle: Along with other calf muscles it is powerful plantarflexor and has a major contribution in running, walking and dancing. It is also a major postural muscle designed to stop the body from falling forwards at the ankle during stance.
What muscles are in the lower leg?
There are many muscles located in the lower leg, but there are three that are particularly well known—the gastrocnemius and the soleus, which are the most powerful muscles in the lower leg, and the anterior tibialis. The Achilles tendon is also located in the lower leg.

Lack of physical activity due to an injury or illness, poor nutrition, genetics, and certain medical conditions can all contribute to muscle atrophy.

Because these two muscles come together above your heel and attach to the Achilles tendon, some providers refer to the gastrocnemius and soleus as one large muscle with two sections. About 10\% of people only have two larger muscles.
What happens to the gastrocnemius muscle when the leg and foot are extended?
gastrocnemius muscle, also called leg triceps, large posterior muscle of the calf of the leg. Action of the gastrocnemius pulls the heel up and thus extends the foot downward; the muscle provides the propelling force in running and jumping. …
What is the insertion of the gastrocnemius muscle?

| Origin | Lateral head: Posterolateral aspect of lateral condyle of the femur Medial head: Posterior surface of medial femoral condyle, popliteal surface of femoral shaft |
|---|---|
| Insertion | Posterior surface of the calcaneus via the calcaneal tendon |
| Innervation | Tibial nerve (S1, S2) |
