The process by which an action potential in the plasma membrane of a myocardial cell triggers the events that directly cause contraction of the myocardial cells is referred to as:
A) electrocontraction.
B) intercalated communication.
C) excitation-contraction coupling.
D) myosin communication.

Question

Quizplus · Accepted Answer

Excitation-contraction coupling is the physiological process where an electrical stimulus (action potential) leads to muscle contraction, specifically in myocardial cells.
