Cardiac muscle ____.

Question

Quizplus · Accepted Answer

Cardiac muscle is self-exciting, meaning it can generate its own electrical impulses without the need for external stimulation. This allows for coordinated contractions and pumping of blood throughout the body. The other options are incorrect. Cardiac muscle is not under voluntary control, as it is controlled by the autonomic nervous system. It also contracts and relaxes quickly, allowing for the rapid pumping of blood. It is not attached to bones, as skeletal muscle is, and does not produce peristalsis, as smooth muscle does.
