The average resting membrane potential of an axon is
A)-70mV.
B)-85mV.
C)0 mV
D)+30mV.

Question

Quizplus · Accepted Answer

The resting membrane potential of axons is typically around -70mV, which indicates that the inside of the cell is negatively charged relative to the outside. This is maintained through the action of ion channels and pumps that keep the balance of ions across the membrane. Choices B, C, and D are incorrect as they are not consistent with the expected value and direction of the resting membrane potential.
