Answer:
The muscular system
Explanation:
The muscular system is a set of muscles that can be controlled voluntarily by a living organism (skeletal muscles) Its main function is to achieve mobility, an action that takes place when electrical stimuli from the nervous system cause the contraction of muscle fibers . Muscles that contract automatically such as heart muscle or smooth muscles are not usually considered part of the muscular system. The whole skeletal musculature corresponds to approximately 40% of the weight of an adult man. The sum of the muscular system plus the bone system formed by the bones gives rise to the musculoskeletal system.
