<P> Cutaneous mechanoreceptors respond to mechanical stimuli that result from physical interaction, including pressure and vibration . They are located in the skin, like other cutaneous receptors . They are all innervated by Aβ fibers, except the mechanorecepting free nerve endings, which are innervated by Aδ fibers . Cutaneous mechanoreceptors can be categorized by morphology, by what kind of sensation they perceive, and by the rate of adaptation . Furthermore, each has a different receptive field . </P> <Ul> <Li> The Slowly Adapting type 1 (SA1) mechanoreceptor, with the Merkel corpuscle end - organ, underlies the perception of form and roughness on the skin . They have small receptive fields and produce sustained responses to static stimulation . </Li> <Li> The Slowly Adapting type 2 (SA2) mechanoreceptors, with the Ruffini corpuscle end - organ, respond to skin stretch, but have not been closely linked to either proprioceptive or mechanoreceptive roles in perception . They also produce sustained responses to static stimulation, but have large receptive fields . </Li> <Li> The Rapidly Adapting (RA) or Meissner corpuscle end - organ mechanoreceptor underlies the perception of flutter and slip on the skin . They have small receptive fields and produce transient responses to the onset and offset of stimulation . </Li> <Li> The Pacinian corpuscle or Vater - Pacinian corpuscles or Lamellar corpuscles underlie the perception of high frequency vibration . They also produce transient responses, but have large receptive fields . </Li> </Ul> <Li> The Slowly Adapting type 1 (SA1) mechanoreceptor, with the Merkel corpuscle end - organ, underlies the perception of form and roughness on the skin .

These receptors in the skin detect pressure pain and temperature
