Question

Quizplus · Accepted Answer

Cardiac muscle forms the walls of the heart chambers and is responsible for pumping blood through blood vessels. It is involuntary and does not require nerve impulses to contract, as it has its own pacemaker cells. Intercalated discs are specialized connections, not nuclei. The heart valves do not contain cardiac muscle.
