Answer: Muscular system.
Explanation:
Muscle tissue is composed of elongated cells, which contain a large amount of contractile protein cytoplasmic filaments, which generate the forces necessary for contraction of this tissue using the energy contained in the ATP molecules. The muscle cell is under the control of the nervous system. Each muscle has its motor nerve, which is divided into many To control all muscle cells, these divisions end in a specialized mechanism called the motor plate.
Muscle cells specialize in contraction and relaxation. These cells cluster in bundles to form muscles. In a very general way, we can define a muscle as an organ with contractile property, ie to shorten its length by a stimulus.
