EVERYDAY SCIENCE

Detailed explanation-1: -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-2: -Exteroceptors provide pressure, temperature, and touch information, and the senses of equilibrium (balance), hearing, sight, smell, and taste. Proprioceptors monitor skeletal muscle and joint movement and positioning. Somatic afferent fibers carry data from proprioceptors and exteroceptors.

Detailed explanation-3: -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-4: -Exteroceptors occur at or near the surface of the skin and are sensitive to stimuli occurring outside or on the surface of the body. These receptors include those for tactile sensations, such as touch, pain, and temperature, as well as those for vision, hearing, smell, and taste.

Detailed explanation-5: -Chemoreceptors respond to chemicals in taste and smell and in internal changes. Thermoreceptors respond to temperature changes. Mechanoreceptors respond to physical forces in touch, hearing, and pressure. Photoreceptors respond to light.
