Summary of  Smooth Muscles vs Cardiac Muscles

1.Cardiac muscles are striated unlike smooth muscles.

2.Cardiac muscles are found in the heart walls and aorta while smooth muscles are found in the majority of blood vessels and internal organs.

3.The cardiac muscle is innervated by the autonomic nervous system via its cardiac pacemaker while smooth muscles are directly innervated by this system.

4.Cardiac muscles do not regenerate when injured unlike the smooth muscles.
