Anatomy The posterior tibial tendon is one of the most important tendons of the leg. A tendon attaches muscles to bones, and the posterior tibial tendon attaches the calf muscle to the bones on the inside of the foot. The main function of the tendon is to hold up the arch and support the foot when walking.

Cold For example, picking up a book that has been handled by someone with a cold or playing cards with someone who has a cold can result in a person catching a cold. What Parts of the Body Do Cold Viruses Affect? Cold viruses attack the mucous linings of the nose and throat, and sometimes the eye. The tissues in the nose and throat become inflamed from the infection. The nose is stuffy, and it is hard to breathe.

Gastrocnemius Gastrocnemius. The gastrocnemius muscle is a muscle located on the back portion of the lower leg, being one of the two major muscles that make up the calf. The other major calf muscle, the soleus muscle, is a flat muscle that lies underneath the gastrocnemius.

Calf Stretches Calf stretches can really help reduce knee pain and improve flexibility. The calf is made up of two muscles on the back of your lower leg, gastrocnemius (which starts just above the knee) and soleus (which starts just below the knee). The calf muscles main job is to pull the foot down, like when you point your toes.You have to stretch the two muscles in a slightly different way, with a straight knee to bias gastrocnemius and with a bent knee to bias soleus.Here you will find a selection of calf stretches to stretch both the muscles on the back of your lower leg which can help relieve knee pain and prevent injuries.ou have to stretch the two muscles in a slightly different way, with a straight knee to bias gastrocnemius and with a bent knee to bias soleus.

Glossary of Foot & Ankle Terms Achilles tendon - The Achilles tendon connects the three strongest flexor muscles of the leg to the foot. It is a tendon that connects the two heads of the gastrocnemius muscle and the deeper soleus muscle to the calcaneus, or heel bone. The Achilles can be felt in the back of the ankle and is just under the skin. This tendon is a common source of pain in runners and other athletes.

Major Muscles on the Front of the Body The large muscle of the posterior part of the lower leg. It is the most superficial of the calf muscles. The gastrocnemius has 2 heads, one originating along the outside of the head and condyle of the femur and the other originating along the medial popliteal surface of the femur.

What Are the Functions of the Calf Muscle? SHARE SHARE TWEET EMAIL. The calf muscle is made up of seven muscles arranged into superficial and deep groups. The superficial group includes the gastrocnemius, plantaris and soleus. The gastrocnemius is the most visible muscle, and it gives your calf most of its shape.The deep group includes the popliteus, flexor digitorum longus, flexor hallucis longis and the tibialis posterior.he gastrocnemius is the most visible muscle, and it gives your calf most of its shape.

Gastrocnemius muscle Along with the soleus muscle, the gastrocnemius forms half of the calf muscle. Its function is plantar flexing the foot at the ankle joint and flexing the leg at the knee joint. The gastrocnemius is primarily involved in running, jumping and other fast movements of leg, and to a lesser degree in walking and standing.

Gastrocnemius Both the gastrocnemius and the soleus run the entire length of the lower leg, connecting behind the knee and at the heel. A third muscle, the plantaris muscle, extends two-to-four inches down from the knee and lies between the gastrocnemius and the soleus.oth the gastrocnemius and the soleus run the entire length of the lower leg, connecting behind the knee and at the heel.

- Calf Strain Causes. The calf muscle group consists of the gastrocnemius muscle and the soleus muscle. These muscles attach to your heel bone via the Achilles tendon and are some of the most used muscles in your body. Calf muscles get tight, plain and simple.

Gastrocnemius The gastrocnemius muscle is a muscle located on the back portion of the lower leg, being one of the two major muscles that make up the calf.The other major calf muscle, the soleus muscle, is a flat muscle that lies underneath the gastrocnemius.he gastrocnemius branches at the top behind the knee; the two branches are known as the medial and lateral heads. The flexing of this muscle during walking and bending of the knee creates traction on the femur, pulling it toward the tibia in the lower leg and causing the knee to bend.

- The calf muscle, on the back of the lower leg, is actually made up of two muscles: 1  The gastrocnemius is the larger calf muscle, forming the bulge visible beneath the skin.  The soleus is a smaller, flat muscle that lies underneath the gastrocnemius muscle.

- Beneath it lies the soleus muscle (Image 1C), which holds the real strength and power in the calf. These two muscles help you to stand, walk, run, and rise up on the balls of your feet. Both are attached to the back of the calcaneous by the Achilles tendon (Image 1D).

7 Common Causes of Calf Pain and How to Treat Them The body region commonly referred to as the calf is in the back of the leg, just below the knee. To better understand potential causes of calf pain, let's first review the anatomy of your calves. The calf is made of three major muscles: the two gastrocnemius muscles (medial and lateral) and the soleus muscle.

- The Achilles tendon connects the calf muscle to the heel bone. The calf muscle is actually two muscles, the gastrocnemius muscle and the soleus muscle. The soleus lies underneath the gastrocnemius. The Achilles tendon is the largest tendon in the body.

Often referred to as the calf muscle, it is located behind the tibia (shin bone) and works across both the knee and ankle joints.

Common Conditions of the Achilles Tendon The Achilles tendon spans two joints and connects the calcaneus to the gastrocnemius and soleus muscles, comprising the largest and strongest muscle complex in the calf (Figure 1) . The tendon is vulnerable to injury because of its limited blood supply, especially when subjected to strong forces. View/Print Figure.

Muscles That Give You Running Speed Calf Muscles. There are two main calf muscles: the gastrocnemius and the soleus. The gastrocnemius is the larger of the two and is responsible for extending your ankle and also weakly flexes your knee.The smaller soleus muscle lies below the gastrocnemius and its sole function is to extend your ankle. These two powerful muscles work together to push you forward off your toes.alf Muscles. There are two main calf muscles: the gastrocnemius and the soleus.

Learn Muscle Anatomy: Muscles of Plantarflexion Triceps Surae. The triceps surae is a group of muscles in the posterior compartment of the distal leg, made up of the gastrocnemius, soleus, and their common tendon, the Achilles tendon; the triceps surae is commonly known as the calf.ne of the most common injuries is ankle sprains, specifically straining the anterior talofibular ligament (ATF). So, the next time you watch a ballet performance (or cringe your way through the movie Black Swan), think of all the muscles working together to lift those graceful dancers up onto their toes.
