\t\t\t• Get their name from their smooth appearance under a microscope.• Arranged in bundles of muscle fibre sheets.• Contract involuntarily. Regulated by autonomic part of nervous system.• Found in walls of hollow structures, including veins, arteries, and intestines.• Maintain flow of fluid and food along hollow structures.• Found in hair erectors, pupils, gland ducts, esophagus, bronchi, intestines, stomach, and blood vessels.• Contract slowly and rhythmically. \t \t\t\t• Found only in heart and at cardiac ends of main blood vessels.• Contract involuntarily.• Striated when viewed under a microscope.• Do not fatigue.• Contract rhythmically.• Controlled by central nervous system, but can contract without signals due to "pacemaker" cells.• Contain high count of mitochondria and myoglobin.• Have good blood supply.\t \t\t\t• Are directly attached to the skeleton by tendons.• Aid in movement and locomotion.• Are voluntarily activated.• Appear striped under a microscope. Also called "striated" muscle.• Fatigue more quickly than smooth or cardiac muscles.• Are able to stretch and resume original shape.• Striated appearance comes from formation of actin and myosin muscle fibres.• Are capable of powerful contractions and, just as adequately, small contractions for delicate movement requiring precision.• Stimulated by the nervous system\'s motor neurons.• Well-supplied with nerves and blood vessels.\t
