Smooth Muscle Definition Smooth muscle is a type of muscle tissue which is used by various systems to apply pressure to vessels and organs. For muscle cell contraction, the initial sources of energy (ATP) are intracellular ATP (4-6 seconds), creatine phosphate (another 10-15 seconds), aerobic metabolism (fatty acids -rest or light exertion, and glucose), and anaerobic metabolism (1 to 2 minutes). They give limited ability for regeneration and possibly growth. Hypertrophy applies to enlarged skeletal muscles. the uterus during pregnancy), cells usually contract spontaneously, but can be stimulated or inhibited by the autonomic NS.
