3 types of vertebrate muscle tissue
But peristaltic contractions of the intestine differ in duration and nature from the muscular contractions which flex your arm, and different types of muscle are used to accomplish each. The three types of muscle found in vertebrates are: (1) smooth, (2) skeletal, and (3) cardiac.All three muscle tissues are composites comprised of (1) muscle cells, (2) connective tissue, (3) nerve fibers, and (4) blood vessels.he muscle cells themselves are elongate, and are often referred to as muscle fibers. These contain the intracellular contractile elements, the myofilaments. The intracellular organization of these elements is greatest in skeletal muscle and least in smooth muscle.
