Muscles are tissues, and tissues are composed of a group of cells. In the case of muscles, the cells are called muscle fibers. If these muscle fibers are grouped, they will initially form a muscle fiber bundle, also known as a fascicle. A group of fascicles comprises a whole muscle. Striations occur due to the alternating dark and light bands
Skeletal muscles are striated, voluntary, and controlled by the somatic nervous system.
Smooth muscles are non-striated, involuntary, and controlled by the autonomic nervous system (parasympathetic and sympathetic).
Cardiac muscles are striated, contain intercalated discs, are involuntary, and are controlled by the autonomic nervous system (parasympathetic and sympathetic).
