Skeletal muscle is attached to bone via tendons, as shown in this diagram. We have the biceps, we have this tendon attached to our bone, we have a tendon on this side also attached to our bone, and our bone is attached to another bone via ligament. Now, the movement of this musculoskeletal system allows for a wide range of motion that is ultimately controlled by our nervous system. So the nervous system coordinates with the musculoskeletal system to basically create this type of voluntary motion. Now, the fourth type of function is in storage as well as mineral homeostasis. So basically, our bone contains special type of tissue known as adipose tissue.
