Description
The psoas major muscle is a large, triangular-shaped muscle located in the abdominal and hip region. It originates at the vertebral bodies and intervertebral discs of the lumbar spine, and inserts into the lesser trochanter of the femur (thigh bone). The psoas major muscle is one of the primary muscles of the hip, and is responsible for flexing the hip joint.
The main function of the psoas major muscle is to flex the hip joint, bringing the thigh towards the chest. This movement is essential for activities such as walking, running, and climbing stairs. The psoas major muscle also helps to stabilize the spine, and can assist in lateral flexion (bending to the side) of the trunk.
In everyday life, the psoas major muscle is used in many activities that involve flexion of the hip, such as walking, running, and climbing stairs. It is also used in activities that require lateral flexion of the trunk, such as reaching for something on a high shelf or performing side bends.
