A contractile cell with a membrane potential of 0 mV is experiencing the:
A) initial repolarization phase.
B) repolarization phase.
C) rapid depolarization phase.
D) plateau phase.

Question

Quizplus · Accepted Answer

The plateau phase is characterized by a membrane potential close to 0 mV, where calcium ions enter the cell, balancing the exit of potassium ions, maintaining the membrane potential at a relatively stable level.
