What are the four different types of general sensory receptors and what is the basis of their classification? ?

Depending upon the type of energy detected by receptors , they can classified into many groups but you need for so I'm going to write here only four with their functions 1. Thermoreceptors: they detect changes in temperature 2. Chemoreceptors: they detect chemicals dissolved in body fluid medium surrounding them. 3. Mechanoreceptors: they detect sound , motion , position in relation to gravity. 4. Photoreceptors: they detect visible and ultra violet light! Hope so it would help!

Your gonna need to upload an image with the question : )
