Please help label the following

**Pelvic Muscles** This diagram provides a detailed view of the pelvic muscles, highlighting key components in the muscular anatomy of the pelvis. The muscles and structures are labeled numerically for easier identification: 1. **Iliacus**: Located on either side of the pelvis, this muscle is essential for flexion and rotation of the thigh. 2. **Iliopsoas**: A major muscle group composed of the iliacus and psoas major, crucial for hip flexion and maintaining posture. 3. **Inguinal Ligament**: A band running from the pubic tubercle to the anterior superior iliac spine, important for structural support. 4. **Psoas Major**: A long muscle on both sides of the lumbar spine, important for flexing the hip joint and raising the thigh. 5. **Quadratus Lumborum**: A muscle of the posterior abdominal wall instrumental in stabilizing the pelvis and spine. **Figure 28.2** illustrates these components of the pelvic muscles, providing a clear understanding of their placement and function.
