Muscles work by contracting and relaxing to create movement and provide support for the body. When a muscle contracts, it pulls on the bones, causing movement at the joints. This process is controlled by signals from the brain and nervous system. Muscles also work together in groups to stabilize the body and maintain posture.

How does the human skeleton enable you to move?
The human skeleton provides structure and support for the body, allowing muscles to attach and create movement at joints. Joints act as pivot points for movement, allowing bones to articulate and muscles to contract and generate force, enabling various types of movement such as walking, running, and bending. Additionally, the skeleton protects vital organs and provides leverage for efficient movement.
What permits body motion?
Body motion is primarily governed by the skeletal system, which provides structure and support for movement. Muscles attached to the skeleton contract and relax to generate movement. Additionally, the nervous system plays a crucial role in coordinating and controlling body movements through signals transmitted from the brain to the muscles.
What systems work together to move your body?
The skeletal system provides structure and support, the muscular system produces movement by contracting and relaxing, the nervous system controls muscular contractions and coordination, and the circulatory system delivers nutrients and oxygen for muscle function. These systems work in coordination to enable movement in the human body.
How do bones act as levers?
Bones act as levers in the body by providing a rigid support for muscles to attach to. When muscles contract, they pull on the bones, creating movement around joints. The length and position of bones determine the leverage and force that muscles can exert to move the body.
What sends electrical signals through the body?
Neurons are specialized cells that send electrical signals through the body. These signals enable communication between different parts of the nervous system and are essential for functions such as movement, sensation, and cognition.
