3. MUSCLE TISSUE consists of fibers (cells) that are modified for contraction (provide motion, maintenance of posture, and heat.)
three types.
Skeletal muscle tissue is attached to bones, is striated, and is voluntary
Cardiac muscle tissue forms most of the heart wall, is striated, and is usually involuntary
Smooth (visceral) muscle tissue is found in the walls of hollow internal structures (blood vessels and viscera), is non-striated, and is usually involuntary. It provides motion (e.g., constriction of blood vessels and airways, propulsion of foods through the gastrointestinal tract, and contraction of the urinary bladder and gallbadder)
