14. Skeletal muscles always work in
what

When skeletal muscles contract, bones move. But how do muscles make your bones move? A voluntary muscle usually works across a joint. It is attached to both the bones on either side of the joint by strong cords called tendons. A tendon is a tough band of connective tissue that connects a muscle to a bone. Tendons are similar to ligaments, except that ligaments join bones to each other. Muscles move the body by contracting against the skeleton. When muscles contract, they get shorter. By contracting, muscles pull on bones and allow the body to move.

Hope this will you to understand the movement of the skeletal muscles
