Muscles and bones together are called the musculoskeletal system of the body.
The bones provide posture and structural support for the body.
The muscles provide the body with the ability to move (by contracting, and generating tension).
The musculoskeletal system also provides protection for the body’s internal organs.
In order to serve their function, bones must be joined together by something. The point where bones connect to one another are called joints, and this connection is made mostly by ligaments (along with the help of muscles), and muscles are attached to the bones by tendons.
Bones, tendons, joints and ligaments don’t possess the ability, as muscles do, to make the body move!
