High threshold mechanoreceptors
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 what kind of sensation they perceive, by the rate of adaptation, and by morphology. Furthermore, each has a … Web1.

WebIntense pressure receptors (IPRs) comprised a group of A-delta afferents with thresholds of 2-16 g. Mechanonociceptors (MNs) comprised a group of relatively slowly conducting afferents (A-delta and C-fibers) with a higher threshold range (16-300 g). 3. In most instances, MNs lacked pressure-transducing capacity. WebMechanoreceptors that possess a large diameter and high myelination are called low-threshold mechanoreceptors.Fibers that respond only to skin movement are termed rapidly adapting mechanoreceptors (RA), while those that respond also to static indentation are termed slowly adapting mechanoreceptors (SA).
