8. How do you distinguish between a skeletal muscle and a cardiac muscle?
The differences between skeletal muscles and cardiac muscles are as follows:
| Skeletal muscle | Cardiac muscle |
| The functions of skeletal muscles are voluntary. | Cardiac muscles function involuntarily. |
| The cells of these muscles are unbranched. | The cells of these muscles are branched. |
| Intercalated discs between the cells are absent. | Intercalated discs between the cells are present. |
| These consist of alternate light and dark bands | These possess faint bands. |
| Rapid contraction takes place due to which they get fatigued. | Although rapid contraction takes place they don't get fatigued too easily in a short duration of time. |
|
They help in locomotory actions and body posture as they are present in body parts such as the legs, hands, etc. |
Cardiac muscles help in the movements of the heart and are present in the heart. |
