• Skeletal muscles are cylindrical in shape and have light and dark bands thus also known as striated muscles. They are voluntary in nature as their movement is controlled by our will power. And are present in our limbs.
• Whereas smooth muscles are spindle shaped and do not have striations over them. They are involuntary in nature and are present in our intestine, blood vessels etc.
