Question:

How do the three parts of skeletal muscle interact with the bones and joints to create movement at the joint?

Answer:

Joints are formed where two or more bones come together. Skeletal muscles attach to the bones that form the joint and contract to create movement. The origin of the muscle is where the muscle starts, and it is fixed. The insertion of the muscle is where the muscle attaches to the moving bone. When the body of the muscle contracts, or shortens, the bone where the muscle is inserted will move at the joint.
