Detailed explanation-1: -Phasic receptors are rapidly adapting receptors. They will respond quickly to stimuli but stop responding upon continuous stimulation.
Detailed explanation-2: -Rapidly adapting, or phasic, receptors respond maximally but briefly to stimuli; their response decreases if the stimulus is maintained. Conversely, slowly adapting, or tonic, receptors keep firing as long as the stimulus is present.
Detailed explanation-3: -What Is Sensory Adaptation? Sensory adaptation is a reduction in sensitivity to a stimulus after constant exposure to it. 1 While sensory adaptation reduces our awareness of a stimulus, it helps free up our attention and resources to attend to other stimuli in our environment.
Detailed explanation-4: -Thermoreceptors. Thermoreceptors can be separated into receptors for warmth and cold detection. According to results of differential nerve blocks and response latencies, the warmth sensation has been attributed to C fibers, whereas cold detection is a function of A fibers.
