Q. According to the stimuli they collect how are the sensory receptors classified?

The sensory receptors are classified according to the stimuli they get: mechanoreceptors are stimulated by pressure (for example sound or touch), chemoreceptors respond to chemical stimuli (olfactory, pH, metabolite concentration, taste, etc.), thermoreceptors are sensitive to temperature changes, photoreceptors are stimulated by light, nocireceptors send pain information proprioceptors are sensitive to the spatial position of muscles and joints as they generate information for the equilibrium of the body.
