Muscles in the Leg

muscles leg

There are many different types of muscles in the leg. Tensor fasciae latae, for example, is a teardrop-shaped muscle that begins on the ASIS (anterior sagittal spine). It flares slightly as it inserts into the fascia. It is sometimes visible as a bulge in the upper leg. When the leg is flexed, it compresses into an egg shape, while it stretches into an oval shape when the leg is extended.

biceps femoris

The biceps femoris muscle is a group of two muscle heads that insert on the head of the fibula. This group of muscles is surrounded by a sheet of fascia that covers the leg. In some people, the biceps femoris can snap. This condition causes pain during 90 degrees of knee flexion and can make ADL (activities of daily living) difficult.

Iliotibial tract

The iliotibial tract is a band of thick connective tissue that runs along the lateral aspect of the thigh. It is part of the deep fascia of the thigh and is derived from the gluteus maximus and tensor fasciae latae muscles. It acts as a stabilizing band, and supports the hip and knee joint. There are multiple clinical conditions that may occur as a result of ITB dysfunction.

Gluteus maximus

The Gluteus maximus is a large muscle in the buttock. It originates from the coccyx and sacrum, and then runs across the iliotibial tract to attach to the upper part of the femur. Its main function is to rotate the thigh outward. It is an essential part of the leg, and requires specific training to ensure that it is functioning correctly.

Semimembranosus

A hamstring injury may involve the semimembranosus muscles. In this case, treatment consists of rest, ice packs, and massaging. Using the affected muscle should also be encouraged in order to promote the growth of new muscle fibers. It is also important to stretch the semimembranosus muscle prior to exercise to prevent injuries. The following are some exercises that will help you strengthen your semimembranosus muscles.

Vastus intermedius

The Vastus intermedius muscle is a part of the leg’s quadriceps group. It has a morphology similar to the vasti muscles, including a flat aponeurosis and proximal muscle belly. The muscle develops into a tendon and merges with the quadriceps femoris tendon at its insertion. A picture of the Vastus intermedius muscle is shown in Figure 2.
