C pain fibers

WebJul 25, 2024 · Visceral pain that is not distinctly localized is carried by the C fibers from the deep structures to the spinal cord. [16] Neuropathic : This persistent pain is often a consequence of damage to these nerve fibers, … WebThe unmyelinated C fibers respond to thermal, mechanical, and chemical stimuli and produce the sensation of dull, diffuse, aching, burning, and delayed pain. The myelinated A-delta fibers respond to mechanical (pressure) stimulus and produce the sensation of sharp, localized, fast pain.

WebAδ fibers carry cold, pressure, and acute pain signals; because they are thin (2–5 μm in diameter) and myelinated, they send impulses faster than unmyelinated C fibers, but more slowly than other, more thickly myelinated group A nerve fibers. Their conduction velocities are moderate. [8] WebJul 25, 2024 · C fibers are smaller, unmyelinated fibers that require a higher threshold of stimulus than A-delta fibers. These are responsible for the slower onset of deeper pain after an initial insult relayed by the faster A-delta fibers.
