Sensory receptors occur in specialized organs such as the eyes, ears, nose, and mouth, as well as internal organs. Each receptor type conveys a distinct sensory modality to integrate into a single perceptual frame eventually.
Or, put more succinctly:
The sense organs contain groups of specialized cells called receptor cells which produce electrical impulses in response to specific stimuli.
