PATHOLOGY

Detailed explanation-1: -According to the activating stimulus sensory receptors can be classified into electromagnetic receptors (photoreceptor, thermoreceptor), mechanoreceptors (hearing, touch, balance, osmoreceptor), and chemoreceptors (odorant receptor, gustatory receptor).

Detailed explanation-2: -Examples of various receptor nerve cells include rods and cones (vision), Meissner’s corpuscles (touch), olfactory cells (smell), hair cells (hearing), and gustatory cells (taste).

Detailed explanation-3: -Receptors of vision. The retinal is the principal molecule of vision in the retina. Receptors of hearing. Receptors of balance. Receptors of taste. Receptors of smell. Receptors on the skin.
