What is the function of receptors in our body? Think of situations where receptors do not work properly. What problems are likely to arise?
Receptors are transducers which exhibits sensitivity in various body parts. When our body receives any external or internal stimuli, it converts stimuli into nerve impulses (action potential) and send these impulses to other neurons, muscle fibres or glands.
If the receptors get damaged they will not detect the stimulus, as well our brain also will not detect the signals which will be harmful for our body (Eg. When we touch an cold or hot object or to getting burnt etc.)
