- 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.oth 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.

Triceps surae muscle Structure[edit] The two muscle layers that make up the triceps surae, namely the gastrocnemius and soleus. The triceps surae is connected to the foot through the Achilles tendon, and has 3 heads deriving from the 2 major masses of muscle. The superficial portion (the gastrocnemius) gives off 2 heads attaching to the base of the femur directly above the knee.

Gastrocnemius muscle The gastrocnemius is located with the soleus in the posterior (back) compartment of the leg. The lateral head originates from the lateral condyle of the femur, while the medial head originates from the medial condyle of the femur.

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.

Background One mechanism that occurs is on the back leg during a lunging shot, in which the knee is extended while the foot is dorsiflexed. This action puts maximal tension on the gastrocnemius muscle as the lengthened muscle is contracted at the push off, resulting in a medial calf injury. (See also the Medscape Reference article Calf Augmentation.)

Muscles Vastus medialis: This teardrop-shaped muscle of the inner thigh attaches along the femur and down to the inner border of the kneecap. It aids in knee extension. Vastus intermedius: Between the vastus medialis and the vastus lateralis at the front of the femur, it is the deepest of the four quadriceps muscles.

The Anatomy of the Gastrocnemius Muscle The gastrocnemius inserts at the calcaneous bone of the heel of the foot by way of the Achilles tendon. Achilles Tendon. Muscles insert to bone through their tendons. Muscle bundles are surrounded by filmy connective tissues. These connective tissues extend from the muscle and gather to form tendons. Tendons are denser and more fibrous than muscle.

Picture of the Calf Muscle 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. 2  The soleus is a smaller, flat muscle that lies underneath the gastrocnemius muscle.

- This study verified that the gastrocnemius muscle is an antagonist of the ACL. Since the gastrocnemius is a flexor of the knee, this finding may have important clinical ramifications in ACL rehabilitation since flexor torques are generally thought to be protective of a healing ACL graft.[PubMed-indexed for MEDLINE].he gastrocnemius muscle is an antagonist of the anterior cruciate ligament.

Check your stateâs scope-of-practice requirements for podiatrists allowed to treat gastrocnemius equinus. A gastrocnemius recession is performed on a patient with gastrocnemius equinus (tightness of the calf muscle) to lengthen the calf muscle. The tightness in the gastrocnemius muscle causes the ankle to point downward, meaning the joint cannot dorsiflex (bend up) normally.

LA Fitness Will Say Anything To Avoid Honoring Free 3 Day Pass I hate doing cardio so the one and only element I look for in a gym is a swimming pool. After a quick search, I realize that the only club capable of offering a pool around my house is L.A. Fitness. So yesterday I printed out my “3 day free pass” and headed out there.

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.he 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. Both the gastrocnemius muscle and the soleus join onto the Achilles tendon, which is the strongest and thickest tendon in the human body.

Medial Gastrocnemius Strain A medial gastrocnemius strain (MGS) is a specific type of injury to the calf muscle in the back of the leg. A muscle strain occurs when the muscle is stretched too far, which causes tears to occur within the muscle. A calf strain occurs when the muscle in the back of the leg sustains this type of injury.

- It comes from two immovable ends (or heads) located on the femur, one on the side (lateral) and one toward the center (medial). The far end of this muscle joins the strong Achilles tendon, which descends to the heel and attaches to the calcaneus.

calf calf the twin 'bellies' of the gastrocnemius are prominent in the upper half of the calf, e.g. when standing on tip-toe; this and the flatter soleus in front of it (known together as the triceps surae) form the main bulk of the calf muscles; their tendons join to attach to the calcaneum via the Achilles tendon.
