There are different receptors in each sense organs. One is general receptors and other is special receptors.

  • Skin contains general receptors
  • Mouth and nose contain a special receptors chemoreceptors (chemical receptors)
  • Eyes also contain a special receptors photoreceptors (light receptors)
  • Ears contain mechanoreceptors which are also a special receptor.

5 senses of the body and their functions


A good sense of sight is achieved by healthy eyes. Eyes are the organs of the visual system of our body. Our body can have different different eye colours depending on the amount of melanin present in our body and the eye color can vary from brown to blue.

  2. The images actually sent are upside down but our brain help to understand what it is by turning the image on the right side up.
  3. The cones and the rods are the two types of light-sensitive cells in the retina. When the cones distinguish colours, the rods allow us to see better in dim light. And, by the optic nerve, all of this information is sent to the brain.

  2. The hearing is the motion of the vibrations detected in the inner ear through a series of tiny bones to tiny hairs.
  3. The ear uses bones, hairs, and fluid to convert sound waves into sound signals.
