Well, one of the predominant functions of our skeletal system is basically bodily movements that are voluntary. So the skeletal system coordinates with the muscular system, skeletal muscle, as well as with the nervous system to basically coordinate different types of voluntary movements such as walking, running, swimming, riding a bicycle and so forth. So, anytime we can voluntarily move our body, this involves not only skeletal muscle and the nervous system, it also involves our skeletal system. In fact, our skeletal muscles are connected to bones via filaments known as our tendons. And bones are connected to other bones via filaments, known as ligaments, that also consist in certain regions of joints that basically act to absorb some of that force, some of that shock. So basically, the skeletal system, coupled with the skeletal muscle and together known as the musculoskeletal system, is responsible for voluntary movements such as walking.
