What type of tissue makes up the muscles in your arms and legs?

The muscles in your arms and legs are composed of skeletal muscle tissue. Skeletal muscle is one of three types of muscles, along with smooth and cardiac muscle. Skeletal muscle is attached to bones and is responsible for voluntary movement. It is characterized by its striated appearance, which is caused by the arrangement of actin and myosin filaments within the muscle fibers. Skeletal muscle is also known as voluntary muscle because it can be consciously controlled by the nervous system.
