LTMRs are classified based on their response … WebIt is widely believed that low threshold mechanoreceptors are involved in non-painful sensation from the bladder and contribute to reflex regulation of bladder contractility. In contrast, high threshold afferents mediate discomfort and painful sensations from the bladder (de Groat, 2006; Janig 2006). However, this division has numerous pitfalls. canfield ohio tax form
