A change in the resting potential from -70 mV to -73 mV is called:
A) depolarization.
B) hyperpolarization.
C) graded excitatory potential.
D) nothing, as these changes occur spontaneously.
Hyperpolarization
A change in a cell's membrane potential that makes it more negative, usually making it less likely to fire an action potential.
Resting Potential
The difference in electric charge between the inside and outside of a neuron's cell membrane when the neuron is not actively transmitting a signal.
Depolarization
The process in which the difference in electrical charge across a cell membrane decreases, often leading to the initiation of an electrical signal.
