Question
Chapter 19.4, Problem 6AYLO
Summary Introduction
To discuss:
The cardiomyocyte resting potential and the actions of gated sodium calcium potassium channels and their movements. Difference between the myocardial action potential and neurons. Long refractory period of myocardial action potentials that support the pumping effectiveness of the heart.
Introduction:
Cardiomyocytes are the cells that make up the cardiac muscles. They are highly elastic and membrane-conducting potential like that of neurons. These cardiomyocytes play an intriguing role in membrane potential capability in heart and heart beat impulse conductivity.
