Question

Cardiac muscles are said to be involuntary muscles. Give reasons.

Answer 1

Cardiac muscles are said to be the involuntary muscles as they are not in our controls. 

Those muscles which are in ours controls are called as the voluntary muscles and those muscles which are not in ours controls are called as the Involuntary muscles. 

Cardiac muscles are the muscles of the hearts. We cannot stop them. I means we cannot make any changes in there working. If they are running we cannot stop them If they are stopped we cannot run them.


Thus, we are not having any controls on cardiac muscles (or Heats muscles),  Hence, they are called as the Involuntary muscles.
