An electrical charge applied to an axon that moves the membrane potential from -70 mV to -45 mV will result in a(n)
A) action potential.
B) local potential.
C) downward shift of the threshold of excitation.
D) upward shift of the membrane threshold.
E) long-term change in the membrane potential.

Question

Quizplus · Accepted Answer

When the membrane potential reaches -45 mV, it crosses the threshold of excitation and triggers an action potential.
