MUSCULUS ILIACUS Meaning and
Definition
-
The musculus iliacus, also known as the iliac muscle, is a primary flexor of the hip joint formed by the combination of the iliacus and the psoas major muscles. It is one of the major muscles of the anterior abdominal wall and is located deep within the pelvis and anterior to the hip joint. The musculus iliacus originates from the iliac fossa, which is the concave surface of the iliac bone located on the inner aspect of the upper pelvis. It extends downwards and joins the psoas major muscle at the level of the inguinal ligament to form the iliopsoas muscle.
The function of the musculus iliacus is to flex and stabilize the hip joint when the leg is lifted, and it also plays a role in maintaining the normal upright posture of the body. It is responsible for movements such as walking, running, and climbing stairs. Additionally, the musculus iliacus assists in forward tilting of the pelvis in movements involving the trunk, such as sitting up from a lying down position.
Injuries or inflammation of the musculus iliacus can cause discomfort and pain in the hip region, limiting its range of motion. Physiotherapy exercises, stretching, and strengthening programs can help in the rehabilitation and recovery of the musculus iliacus, improving its function and reducing pain.
