A change in the resting potential from -70 mV to -65 mV is called:

A) depolarization.
B) hyperpolarization.
C) graded excitatory potential.
D) nothing, as these changes occur spontaneously.

Depolarization

The process in which a cell's membrane potential becomes less negative, moving towards zero, typically initiating nerve impulses or muscle contractions.

Resting Potential

Electrical charge across the insulating cell membrane in the absence of stimulation; a store of potential energy produced by a greater negative charge on the intracellular side relative to the extracellular side.

Hyperpolarization

An increase in a cell's membrane potential, making it more negative and decreasing the likelihood of generating an action potential.
