About this document
Fast vs. Slow Pain Sensations Explained by Soleh Ramly is a document available to read on EtoBox.
This document discusses the differences between slow pain and fast pain sensation. Slow pain is sensed by unmyelinated C fibers and has a transmission rate of 0.5-2 m/sec, causing a long duration sensation that is poorly localized. Fast pain is sensed by thin myelinated A-δ fibers and transmits at 12-30 m/sec, resulting in a short sensation that is well localized. Evidence shows that small doses of local anesthetics block C-fibers and destroy A-δ fibers, eliminating slow pain but leaving fast pain intact.
