_____ is 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.
A) Electrocontraction
B) Intercalated communication
C) Excitation-contraction coupling
D) Myosin communication

Question

Quizplus · Accepted Answer

Excitation-contraction coupling is the process by which an action potential in the plasma membrane of the muscle fiber triggers the cycle,leading to cross-bridge activity and contraction.
Excitation-contraction coupling,not electrocontraction,is the process by which an action potential in the plasma membrane of the muscle fiber triggers the cycle,leading to cross-bridge activity and contraction.
Excitation-contraction coupling,not intercalated communication,is the process by which an action potential in the plasma membrane of the muscle fiber triggers the cycle,leading to cross-bridge activity and contraction.
