Question

Quizplus · Accepted Answer

Cardiac muscle has automaticity, meaning it can generate its own electrical impulses without external nerve stimulation. Smooth muscle, on the other hand, does not have this ability and requires nerve signals to contract. Therefore, there is a difference between the two types of muscle. Neither A nor C are correct as they do not differentiate between the two types of muscle, and D is incorrect.
