Question

What different types of sense organs we have? Discuss briefly.

Answer 1

Human beings have five major sense organs that perceive external stimuli and relay impulses to the brain:

1. Eyes: Organs of sight containing photoreceptors (rods and cones) that detect light and form visual images.
2. Ears: Organs of hearing and balance containing auditory receptors and mechanoreceptors.
3. Nose: Organ of smell containing olfactory chemoreceptors to perceive odours.
4. Tongue: Organ of taste containing gustatory chemoreceptors located on taste buds.
5. Skin: Organ of touch containing mechanoreceptors and thermoreceptors that detect touch, pressure, heat, and cold.
