Sensory impulses originate at receptors in response to
A)neurotransmitters.
B)decreasing permeability of nerve cell membranes.
C)subthreshold potential.
D)local changes in their cell membrane potentials.

Question

Quizplus · Accepted Answer

Sensory impulses originate from receptors due to local changes in their cell membrane potentials. When a stimulus alters the membrane potential of a receptor cell, it generates a localized change in potential that can initiate an action potential to travel to the central nervous system. The other options (A, B, and C) do not accurately describe the process of sensory impulse generation.
