I find it fascinating when Orthopedician (Bones & Joints doctors) colleagues of mine pick up a skeleton to explain what problem you have.
Skeleton is a stationary structure. It's like a hanger. It’s the muscles and tendons, with a lot of help from ligaments, that’ll help you move them, bringing the message to move via the nerves, only after a spark from the brain.
And you thought you had a brain to study so you could earn some money. Use it first so that brain of yours can have an amazing home, not a sloppy crappy one.
