Definitions:

Sensory Receptors

Highly specialized cells in the sense organs that detect and respond to one type of sensory stimulus—light, sound, or odor, for example—and transduce (convert) the stimuli into neural impulses.

Stimulus

A stimulus is any event or situation that evokes a response from an organism.

Sensation

The process of detecting physical stimuli from the environment and converting them into neural signals that the brain can interpret.

Threshold

The point of intensity at which a stimulus becomes detectable to an individual or evokes a response.
