Receptors are sensory structures (organs/tissues or cells) present all over the body. The receptors are either grouped in case of eye or ear, or scattered in case of skin.
Functions of receptors:
(i) They sense the external stimuli such as heat or pain.
(ii) They also trigger an impulse in the sensory neuron which sends message to the spinal cord.
When the receptors are damaged, the external stimuli transferring signals to the brain are not felt. For example, in the case of damaged receptors, if we accidentally touch any hot object, then our hands might get burnt as damaged receptors cannot perceive the external stimuli of heat and pain.

The functions of receptors are -
1. Receptors that are present in our body recieves the information of changes that takes place in our environment.
2. The recieved information is then passed to CNS as nerve impulses where the effectors responses.
If our receptors do not work in a proper manner, then the stimuli given by the environment will not be recieved and then no nerve impulse will be generated and hence our body will not show any response.
