- A-delta fibers are lightly myelinated and have small receptive fields, which allow them to alert the body to the presence of pain. Due to the higher degree of myelination compared to C-fibers, these fibers are responsible for the initial perception of pain.Learn more:A-delta fibers are lightly myelinated and have small receptive fields, which allow them to alert the body to the presence of pain. Due to the higher degree of myelination compared to C-fibers, these fibers are responsible for the initial perception of pain.www.ncbi.nlm.nih.gov/books/NBK470255/A delta pain fibers have thin myelination, whereas C fibers have none. This allows A delta fibers to transmit information to the CNS faster, resulting in the perception of the sharp, first pain after an injury. C fibers transmit information slower, causing the dull, aching, second pain perception.openbooks.lib.msu.edu/introneuroscience1/chapter…A delta fibers are myelinated whereas C fibers are unmyelinated. Because of these anatomical features, painful stimuli from A delta fibers arrive in the central nervous system before those same painful stimuli from the C fibers arrive. The A delta fibers therefore send the “first pain” into the brain, while the C fibers send the slower pain.brainstuff.org/blog/adelta-c-fibers-difference-pain-in…The A-delta nociceptors, comprising up to 25 percent of nociceptors, are found in skin and muscle, and mediate the sharp, sudden pain that is associated with injury such as a cut, trauma, or pain in the abdominal wall.www.uptodate.com/contents/anterior-cutaneous-ne…
