Which muscle attaches to the Anterior Inferior Iliac Spine (AIIS)?

The Rectus Femoris muscle attaches to the Anterior Inferior Iliac Spine (AIIS). This muscle is one of the four components of the quadriceps femoris group and is unique because it also crosses the hip joint, allowing it to act in both hip flexion and knee extension. The origin at the AIIS is crucial as it provides a powerful attachment point that contributes to the function of this muscle during activities such as running, jumping, and kicking.

Understanding the role of the Rectus Femoris and its attachment site is important in the context of biomechanics and rehabilitation, particularly when addressing injuries that may affect the hip or knee.
