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 … WebSep 5, 2024 · This range sensing divides into two groups: low-threshold mechanoreceptors (LTMRs) and high-threshold mechanoreceptors …

In contrast, high threshold afferents mediate discomfort and painful sensations from the bladder (de Groat, 2006; Janig 2006). However, this division has numerous pitfalls.
