Muscle, External Iliacus (M. Iliacus Externus)

The external iliac muscle - M. Iliac Externus (207, 53) - is a muscle of the skeletal system, represented by two elongated and thickened triangular muscle masses, attached at one end to the anterior surface of the sacrum or lumbar vertebrae, the other lower end - to the lateral surface of the femur, and the upper free end (spinous tubercle) - to the inguinal ligament. Divided into posterior and anterior branches. The inguinal bursa of the adjacent organs is inserted into the muscle belly. These muscles form the walls of the inguinal canals along with their contents and fascia. The anterior portion of these muscles rotates the hips outward, lifts the lower part of the abdominal wall, straining the aponeurosis of the internal oblique and transverse abdominal muscles.

The anterior fibers participate in the bending of the spine by contracting the anterior external iliacus muscle, as well as in flexion of the cervical vertebrae. The anterior rami secretes contraction of the deep muscles of the anterior lower limb, such as the rectus femoris, patella, and biceps calf. The transverse fibers of the external iliac muscles and their large bundles help the internal muscle fibers to raise the lower half of the body and lower the upper part of the pelvis. The superficial muscle is of greater importance for activity. The anterior iliac ligaments can connect the abdominal wall, increasing range of motion in the groin and hip joint. Adults require less joint space and are able to walk with straight knees. It counters the stronger rectus femoris and is more active and active in transmitting force during heavy lifts.

During sports/fitness training and surgical operations, the adductor rope can be mobilized through the vagina. This area usually adapts between 13-18 years of age. Inflammation of the perigenital skin and traumatic defects can occur at the site of muscle innervation.
