MusclesMuscles are in everybody in the world. Me. Your brother. Your mother. Stanley. Anyone. Muscles are a band or bundle of fibrous tissue in a human or animal body that has the ability to contract producing movement or maintaining the position of the parts in your body, also keeping them from falling out.

Three types of muscle

There are three types of muscles. Smooth, Skeletal and Cardiac. Smooth its not controlled by our conscious mind. It is found on the walls of many organs and structures such as the stomach, intestines, bladder, and blood vessels. Smooth muscles contract to move substances such as food through the organ. Skeletal muscles are voluntary muscles that control nearly every action a person intentionally performs. Tendons attach the muscle to two bones across a joint, as one muscle contracts the other relaxes which moves the bones. Cardiac is only found in the heart and is responsible to keep it pumping.
