Concept explainers
To discuss:
The three categories of receptors classified by origin of their stimuli.
Introduction:
Structures that are specialized for the detection of a stimulus, such as pain and heat, are referred to as a sensory receptor. Such receptors can either be real sense organs or simple nerve endings. Sense organs, much complex structures containing receptors, combines with other tissues, such as muscular, epithelial and connective tissues, and with nervous tissues. The nervous tissues enhances the response of the sense organs to a particular kind of stimulus. Sense organs are involved in the transmission of data (through neurons) to the specific place inside the nervous system. Such sense organs may range from simple microscopic structures like dendrites to complex structures like the ear and the eye.
