Muscles are essential for movement because they contract and relax to exert force on the bones, enabling the body to perform various activities. This contraction is controlled by the nervous system, which signals the muscles to respond accordingly. Without muscles, the body would lack the ability to produce movement, as bones alone do not have the capability to generate motion. Thus, muscles play a crucial role in locomotion, posture, and all physical activities.
