1.Skeletal muscles are attached to the bones. Smooth muscles line up the visceral organs viz. Intestines,blood vessels,pupils etc (therefore also known as visceral muscles.) 2.Skeletal muscles perform voluntary actions. Smooth muscles are responsible for involuntary reflexes and actions.
Answers. Best Answer: skeletal and cardiac muscle cells are striated which means that there is overlap between actin and myosin filaments. there is also a high degree or organization of these filaments into sarcomeres.smooth muscle cells have no such striations and the cells are spindle-shaped.smooth muscle cells contract slower and for longer periods of time (think of the intestines).ardiac muscle cells also have intercalated discs that allow for rapid propagation of impulses. skeletal muscles contract much faster than cardiac muscle cells and also have a shorter refractory period. as a result of a longer refractory period, cardiac muscle cells cannot show wave summation and tetany.
