Bones provide a framework for muscles to attach to and act as levers for movement. Muscles contract and pull on the bones, causing movement. Together, bones and muscles work in coordination to support movement and maintain the body's structure.

Multiple levers in your body, such as joints, tendons, and muscles, work together to create more efficient movement and increase speed. By distributing the force generated by your muscles across different levers, you can amplify the overall power and speed of your movements. This allows for more coordinated and rapid actions in various parts of your body.
Muscles must work together because you need to move your body.

Your brain controls how your muscles work by sending signals.
Muscles, bones and tendons work together to move your arm. The tendons will connect the muscles to the bones and the bones will provide the necessary support which will facilitate the movement.
Muscles that work together are call synergists. Those that work opposite are called antagonists.
Levers are formed when muscles and bone act together. A lever is a rigid rod that turns a joint and is used so that a small force can move a much bigger force.
