Answer :
Animal muscles' internal structures have been specifically adapted to use contraction to cause movement.
Muscle cells are designed to contract. Muscles enable motions such as walking, as well as bodily processes such as respiration and digestion. Muscle tissue is classified into three types in the body: skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscle tissue develops into skeletal muscles, which attach to bones or skin and control locomotion and any consciously controlled movement.
Skeletal muscle is also known as voluntary muscle because it can be controlled by thought. Skeletal muscles are long and cylindrical in shape; when examined under a microscope, skeletal muscle tissue appears striped or striated. To stay alive, grow, and reproduce, an animal must find food, water, and oxygen, as well as eliminate metabolic waste.
