Difference Between Tonic and Phasic Receptors

What are Tonic Receptors?

The tonic receptors are a type of receptors that show gradual adaptation and provide information about the duration of a stimulus. They typically continue to respond as long as the stimulus persists resulting in a continuous frequency of the action potentials. As a result, tonic receptors convey information about the duration of the stimuli. The response of these receptors is relatively slow....

What are Phasic Receptors?

The Phasic receptors are a type of the sensory receptors that rapidly adapt and primarily respond to the changes in stimuli. These receptors have a quick response time but stop responding when the stimulus is continuous. As a result their action potentials decrease with prolonged stimulation. Phasic receptors provide information about the intensity of the stimuli rather than their duration. Examples of the phasic receptors include Pacinian corpuscles or lamellar corpuscles which are found in the hairless skin of the mammals....

Conclusion – Difference Between Tonic and Phasic Receptors

In conclusion, tonic receptors exhibit slow adaptation, providing continuous feedback about the duration of stimuli, while phasic receptors rapidly adapt to changes in stimuli, focusing on intensity rather than duration. Together, they play crucial roles in sensory perception, transmitting signals to the central nervous system and contributing to our comprehensive understanding of the environment....
