Obturator Muscle

The Obturator Muscle is one of two muscles that are located on the obturator membrane. The obturator membrane is a muscular aponeurotic wall that separates the abdominal cavity and the pelvic cavity. The Obturator muscle, also known as the obturator externus, is located on the outer surface of the obturator membrane and is one of the most important muscles of the thigh.

The Obturator muscle originates on the outer surface of the pubis and on the anterior surface of the lateral process of the ilium. It is inserted onto the inner surface of the femur and performs the function of externally rotating the femur. In addition, it is also involved in hip abduction (moving the leg to the side) and hip flexion (bending the knee joint).

The Obturator muscle plays an important role in maintaining the stability of the pelvis and hip. Its defects can lead to pain in the pelvis and hip, as well as impaired movement in this area. Some athletes, such as football and hockey players, may be susceptible to obturator muscle injuries due to the high stress placed on the pelvic and hip areas.

Overall, the Obturator muscle is an important element of the anatomy of the human body, ensuring the proper functioning of the legs and hips. A good understanding of its structure and function can help prevent and treat injuries and illnesses associated with this area of ​​the body.



The obturator muscle is one of two muscles that are located on the outer surface of the obturator membrane. It externally rotates the femur and is involved in flexion of the femur and hip joint.

The obturator muscle is one of the largest muscles in the human body. It consists of several muscle bundles that are attached to the femur and other bones of the pelvis. Each muscle bundle consists of muscle fibers that intertwine and form a dense structure.

When the obturator muscle contracts, it externally rotates the femur, causing flexion of the femur and hip joint. This movement helps us walk, run and perform other movements.

However, the obturator muscle can also be used in other movements, such as leg lifts or hip extensions. In addition, it can be used to stabilize the body's position in space.

Overall, the obturator muscle plays an important role in our daily lives and is essential for maintaining the proper functioning of our body.



The obturator internus muscles provide lower abdominal pressure and stabilize the internal abdominal organs. The internal obturator membrane muscle is involved in the fusion of the rectum, closing the opening between the rectum and the anus. The muscles of the obturator internus are also the piriformis muscles. They provide support to the bladder and rectum, helping with urinary continence and preventing urinary incontinence.

It is important to note that the anatomical structure of the obturator muscle is sometimes confused with the obturator muscle. This is not the case in this case either. Muscular circumference of the hip joint
