Biology - Muscle and Skeletal system question?

Can someone help me with this question? My textbook doesn't give me enough details to find the answer:

1. Animal locomotion is accomplished through the force of muscles acting on a rigid ___________ system.

I'm not sure if the answer is just the "skeletal system" or the "musculoskeletal system"

Very vague question. Muscular system works to move the SKELETAL system, is nourished by the CIRCULATORY system, muscles assist in propelling fluids in the CIRCULATORY and LYMPHATIC system, muscles are controlled by the NERVOUS system....plus many, many other types of relationships.....good luck!
