Muscles in the Posterior Compartment of the Leg The gastrocnemius is the most superficial of all the muscles in the posterior leg. It has two heads – medial and lateral, which converge to form a single muscle belly. Attachments: The lateral head originates from the lateral femoral condyle, and medial from the medial condyle.

Background A medial calf injury is a musculotendinous disruption of varying degrees in the medial head of the gastrocnemius muscle that results from an acute, forceful push-off with the foot.This injury occurs commonly in sports activities (eg, hill running, jumping, tennis), but it can occur in any activity.

Gastrocnemius The 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.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.

Muscles Around the Knee 1 Plays a part in stabilizing the knee cap. 2  Rectus femoris—on the front middle of the thigh and covers the other three quad muscles. 3  As a extensor muscle it straightens the leg allowing us to walk, run, jump and squat. Vastus lateralis—part of the quadriceps femoris on the outside-front of the thigh, it extends or straightens the leg and is controlled by the femoral nerve. 2  Vastus intermedius—part of the quadriceps femoris on the center-front of the thigh, it extends or straightens the leg and is controlled by the femoral nerve.

What Muscle Groups Are Used to Flex the Knee? Lower Leg Muscles. You use your popliteus and gastrocnemius to support the major muscles of knee flexion on your upper leg. Your popliteus is a thin, triangular muscle that crosses behind your knee and assists with knee flexion. The popliteus connects from your femur to your tibia.

- 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.

It is the most medial of the vastus group of muscles, the others being vastus intermedius and vastus lateralis. 2  The vastus medialis arises medially along the entire length of the femur, and attaches with the other muscles of the quadriceps in the quadriceps tendon.

Muscles in the Posterior Compartment of the Leg There are four muscles in the deep compartment of the posterior leg. One muscle, the popliteus, acts only on the knee joint. The remaining three muscles (tibialis posterior, flexor hallucis longus and flexor digitorum longus) act on the ankle and foot.

Quadricep Muscle Anatomy Anatomy Chart courtesy of FCIT. The Quadriceps are a group of four muscles that sit on the anterior or front aspect of the thigh. They are the Vastus Medialis, Intermedius and Lateralis and finally the Rectus Femoris. The Quadriceps attach to the front of the tibia and originate at the top of the femur. The exception to this rule is the Rectus Femoris which actually crosses the hip joint and originates on the pelvis.
