Detailed explanation-1: -Answer: Smooth muscle is an involuntary, non-striated type of (vertebrate) muscle capable of slow rhythmic involuntary contractions. Smooth muscle, also called an involuntary muscle, displays no cross stripes when examined under a microscope.
Detailed explanation-2: -Smooth Muscle The non-striated (smooth) muscle cell is spindle-shaped and has one central nucleus. Smooth muscle contracts slowly and rhythmically.
Detailed explanation-3: -Intermediate fibers have some characteristics of both fast and slow twitch fibers. Fast twitch fibers are also called Type II fibers. Fast twitch fibers are the predominant fibers in the body. They respond quickly to stimuli and can generate a good deal of force.
Detailed explanation-4: -At a cellular level, smooth muscle can be described as an involuntary, non-striated muscle. Smooth muscle consists of thick and thin filaments that are not arranged into sarcomeres giving it a non-striated pattern.
Detailed explanation-5: -At a cellular level, smooth muscle functions as an involuntary non-striated muscle.
