A-delta and a-beta fibers
WebA-beta: Fast signals from Merkels and Meissners allow for fine tactile discrimination. Correlations between intensity of stimuli and response strength. A-delta: Smaller and less myelinated, therefore medium speed signals – pain and temperature sensations. C-fibers Small unmyelinated – slow signals WebSep 25, 2024 · A-delta LTMRs (previously termed D-hair nerve fibers) have longitudinal lanceolate endings with a unique, polarized innervation of the caudal aspect of the hair …

WebMay 14, 2024 · Aδ ("A-delta") fibers These are thinly-myelinated. They transmit signals in response to heat and touch. If the stimulus exceeds a certain threshold, the brain interprets these as acute pain. This is "good pain" because it warns you to do something to take care of the problems, e.g., a hot saucepan.

Neuropathic pain is another type of pain secondary to the injury to neuronal structures.
