Detailed explanation-1: -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.
Detailed explanation-2: -External receptors that respond to stimuli from outside the body are called exteroreceptors. Exteroreceptors include olfactory receptors (smell), taste receptors, photoreceptors (vision), hair cells (hearing), thermoreceptors (temperature), and a number of different mechanoreceptors (stretch, distortion).
Detailed explanation-3: -Millions of sensory receptors detect changes, called stimuli, which occur inside and outside the body. They monitor such things as temperature, light, and sound from the external environment.
