Which of the following is NOT one of the hamstring muscles?

The rectus femoris is not one of the hamstring muscles; it is actually part of the quadriceps muscle group located at the front of the thigh. The quadriceps group is primarily involved in extending the knee and assisting with hip flexion, while the hamstrings, which include the biceps femoris, semitendinosus, and semimembranosus, are located at the back of the thigh and are crucial for knee flexion and hip extension. Understanding the anatomy and function of these muscle groups is essential in the context of sports massage, as it allows practitioners to target appropriate areas for treatment and rehabilitation. Proper identification of muscle groups also aids in developing personalized exercise and recovery plans for athletes.
