depending on the position and function, the receptors are mainly classified into 4.
1) teloreceptors- which are concerned with events at a distance, eg, rods and cones , hair cells
2) exteroceptors- which are concerned with external environment at hand. eg, receptors for touch, cold, warmth, smell, sound, sight etc..
3) interoceptors - it is concerned with internal environment. eg, baroceptors in carotid and aortic bodies, osmo receptors in blood vessels.
