There are three types of muscle cells - skeletal, cardiac and smooth.

• The skeletal muscle cells are the ones that form the muscle and help to contract and relax. The muscles for movement to take place. these are voluntary muscles and appears striated when viewed under a microscope.
• The cardiac muscles are the ones that are found in the heart and are involved in the contraction of the heart for pumping the blood and making the heartbeat. These are involuntary muscles and appear striated under the microscope.
• The smooth muscles are the ones that are used to control the involuntary movements in the body except for the heart. Since digestion involves involuntary muscles these are located in the walls of the digestive organs such as stomach and intestine. These muscle cells are non-striated.
