Examples stretch receptors, proprioception receptors, baroreceptors, chemoreceptors etc. Phasic Receptors not monitored continuously, olfaction for example Tonic receptors are slowly adapting receptors that respond for the duration of a stimulus Phasic receptors rapidly adapt to a constant stimulus and turn off.
