What is the function of receptors in our body? Think of situations where receptors do not work properly. What problems are likely to arise?

The specialised tips of some nerve cells that detect the changes in our environment by receiving the stimulus are called receptors. These receptors are usually located in our sense organs, such as inner ear, nose, tongue, skin etc. For example, gustatory receptors (tongue) will detect taste while olfactory receptors (nose) will detect smell.

If receptors are not working properly, the external stimulus won't be able to stimulate receptors and no nerve impulse will be generated. The result will be that the body would not respond to changes in the surroundings.
