Answer:

Connective tissues connect muscles to bones. When muscles contract, the tissue becomes shorter thus producing movement.

Explanation:

The connective tissue is called a tendon when it connects muscles to bones.

Muscles cause movement at the cellular level by a sliding and shortening movement.
This happens with muscles surrounding synovial joints which are responsible for the gross movement of the body in space.

Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten, or remain the same.

Although the term contraction implies shortening, when referring to the muscular system, it means muscle fibers generating tension with the help of motor neurons (the terms twitch tension, twitch force, and fiber contraction are also used).
