| Skeletal muscle | Smooth muscle |
| – Cell are multi nucleated | Each cell contain a singe nucleus |
| – Many striations of alternating light and dark bands | Not striated or faintly striated |
| – Response rapid | Response slow |
| – Response is due to external stimulus | Response is due to internal changes |
| – Fatigue quickly | Fatigue takes long time or may not fatigue at all |
| – Short refraction period | Long refraction period |
| – Controlled by voluntary nervous system | Controlled by autonomic nervous system |
| – Every muscle cell is served by a motor nerve fibre ending in a motor end plate | Served by general nerve network known as plexus |
| – Cylindrical muscle cells | Spindle shaped muscle cells |
| – Longer and wider 1- 50mm long above 10mm diameter | Shorter thinner 0.02-0.5mm long, 5-10mm diameter. |
