The muscle shown in the image is the psoas major, a key muscle in the hip flexor group. It originates from the transverse processes, intervertebral discs, and bodies of T12 to L5 vertebrae, descending to insert on the lesser trochanter of the femur. The psoas major is primarily responsible for flexion at the hip joint, enabling movements like walking and running. It is innervated by the anterior rami of spinal nerves L1-L3. Together with the iliacus, it forms the iliopsoas muscle, a powerful flexor of the thigh.
