Sensory impulses are stimulated at receptors by

Question

Quizplus · Accepted Answer

Sensory impulses are stimulated when there are local changes in the cell membrane potentials of receptors. This change in potential triggers the release of neurotransmitters which carry the stimulus to the next neuron in the pathway. Options A and B refer to processes that occur after the receptor has been stimulated, while subthreshold potential (option C) refers to a potential that is not strong enough to trigger an action potential.
