Receptors are present in all parts of the body, such as skin, eye, nose tongue, etc. They detect the signals and send them to the brain in the form of electrical signals.

If the receptors are damaged, they can't receive the inputs or the signals thus can cause harm to the body in a dangerous situation.

Such as, if a person is walking toward a manhole and the photoreceptors (receptors to hear) are damaged, the person cannot listen to the warnings of other people and can fall into the pit.
