Document Summary

How the pain protective response works- receptors, fibers, pathways. Henry beecher"s idea of the reaction component and what is said about pain. Pain is an ancient evolutionary self-protective phenomenon with well-defined mechanisms in the nervous system. Foot gets near fire the string reaches up to the brain near the pineal gland and it activated the mind response. Warns the organism of potential harm, internal or external. Specific pain receptros identified on the skin. Specific pathways to the brain of myelinated and unmyelinated fibers. As fiber is very fast hard pain but c fiber is milder but more long term. You encounter the stimulus the signal is sent to the brain and you feel the pain. Directing heat onto persons hand and as the heat increases the subject is asked to report when there"s an increase in pain. They created a scale jnd - just notable differences. Very unique in measure but very easy to collabarate.
