Quizplus · Accepted Answer

Tonic receptors, such as those found in the skin, always send a signal, but the frequency of action potentials may increase or decrease in response to stimulation. Phasic receptors, on the other hand, only fire action potentials when the stimulus changes, such as when a touch stimulus is removed. Mechanoreceptors and nociceptors are types of sensory receptors that respond to mechanical and painful stimuli, respectively, but they can be either tonic or phasic.
