|
cardiac muscle fibers that dont contract but instead create and conduc the action potential throughout the heart
|
|
ventricular fibers
|
|
|
contractile fibers
|
|
|
autorhythmic fibers
|
|
|
atrial fibers
|
Explanation:
Detailed explanation-1: -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.
Detailed explanation-2: -Cardiac automaticity also known as autorhythmicity, is the property of the specialized conductive muscle cells of the heart to generate spontaneous cardiac action potentials.
