triple response on skin based on physiology
- 2. Introduction There are subsequently 3 response upon stroking a blend instrument on skin. The first reaction to a skin scratch is a crimson reaction, which appears within ten seconds. succeeded by the edema reaction, also referred to as the wheal reaction, which then develops into a flare reaction or edema spreading. Triple response is the term used to describe these three physiological reactions.
- 3. Physiology These occur due to a variety of responses, mostly the release of substances from nerve terminals and fluid from micro blood vessels. The reddish reaction that occurs right after the stork is caused by capillary dilatation. Increased capillary and postcapillary venule permeability is the cause of the edema reaction. The third happens of the antidromic conduction of the c-fibers, nociceptors information also having some collateral effect arterioles, where they secrete substances like PGRP, histamine. As the impulses goes to the center, some impulses may return to arterioles itself, they are known as axon reflex.
