Which Statement Applies to Phasic Receptors

Question

Which statement applies to phasic receptors
A)They respond to pain stimulus.
B)They signal a change in stimulus intensity.
C)They are slowly adapting receptors.
D)An example is a muscle stretch receptor.

Accepted Answer

Phasic receptors respond to changes in stimuli rather than continuous stimuli. Therefore, they signal a change in stimulus intensity. Examples of phasic receptors include those involved in touch, temperature, and pressure. They are different from tonic receptors, which are slowly adapting receptors that respond to continuous stimuli, such as muscle stretch receptors. Phasic receptors may also respond to pain stimuli, but this is not their defining characteristic.
