Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	They are found in the heart and voluntary
B	They are found in the heart and autorhythmic
C	They are found in the heart and stomach, and are autorhythmic
D	None of the above

Explanation:

Detailed explanation-1: -Cardiac muscle is only found in the heart, and although it is striated like skeletal muscle, it functions involuntarily. Cardiac and most smooth muscles are autorhythmic-they are capable of contracting spontaneously without nervous or hormonal stimulation.

Detailed explanation-2: -Cardiac muscle is an involuntary striated muscle tissue found only in the heart and is responsible for the ability of the heart to pump blood.

Detailed explanation-3: -The correct answer is (c) cells are connected to one another by intercalated discs.

Detailed explanation-4: -The heart displays autorhythmicity: a denervated heart (such as the heart of a cardiac transplant patient) continues to contract spontaneously. Pacemaker cells do not have a stable resting action potential, and it is the spontaneous depolarization of the pacemaker potential that gives the heart its auto-rhythmicity.
