Summary Introduction
To review:
One situation in which sensory neurons are important.
Introduction:
Sensory neurons are the most important part of the nervous system. They help us identify various senses like touch, sound, taste, vision, and odor. They can convert external stimuli into internal electrical impulses.

Describe one situation in which these sensory neurons are important.
Applying a pressure stimulus to the fluid-filled capsule of an isolated Pacinian corpuscle causes a brief burst of action potentials in the afferent neuron, which ceases until the pressure is removed, at which time another brief burst of action potentials occurs. If an experimenter removes the capsule and applies pressure directly to the afferent neuron ending, action potentials are continuously fired during the stimulus. Explain these results in the context ofadaptation.
Explain the various characteristics of a stimulus that sensory receptors provide to the CNS.
