Three basic muscle types are found in the body. Skeletal muscle. Cardiac muscle. Smooth muscle. Characteristics of Muscles. The tongue is the strongest muscle in the body (relative to size). There are about 640 skeletal muscles in the human body. It takes twice as long to lose new muscle if you stop working out than it did to gain it.. Myology:(Muscular system).
