1. Non-striated muscles, also known as smooth muscles, are found in the walls of internal organs such as the stomach, intestines, and blood vessels. Cardiac muscles are found in the heart.
2. Non-striated muscles are involuntary muscles, meaning they are not under conscious control. Cardiac muscles are also involuntary muscles.
3. Non-striated muscles have a smooth appearance under a microscope, while cardiac muscles have a striated appearance due to the presence of alternating light and dark bands.
4. Non-striated muscles have a slower contraction and relaxation rate compared to cardiac muscles, which contract and relax quickly to pump blood throughout the body.
5. Non-striated muscles do not have intercalated discs, which are specialized cell junctions found in cardiac muscles that help coordinate contractions and allow for rapid communication between cells.
6. Non-striated muscles do not have a specific resting membrane potential, while cardiac muscles have a stable resting membrane potential that allows for coordinated contractions.
