Final answer:
The inferior gemellus muscle is the most inferior of the lateral rotator group in the context of our studies, located deep to the gluteus maximus and responsible for lateral rotation of the femur at the hip.
Step-by-step explanation:
The most inferior muscle of the lateral rotator muscles, as per the context of our studies, is the inferior gemellus muscle. This muscle is located deep to the gluteus maximus on the lateral surface of the thigh, and it plays a vital role in laterally rotating the femur at the hip. It works in conjunction with other muscles to control hip movement and is a significant component of the deeper muscles of the hip region.
