All nosiseptor are free nerve endings. Neurophysiology research has demonstrated the existence of free nerve endings are very sensitive that only accept itching sensation. This sensation is transmitted through small nerve fibers that had no myelin. There are allegations that the purpose of this itching sensation to give attention to the surface of a light stimulus, such as the propagation lice on skin or mosquito bites, and afferent signals received after the exit of the dorsal root spinal cord substansia grisea, will cross to the opposite side and go up through substansia alba anterior and lateral spinal cord to end in the brain stem in all heights and also in the thalamus, which then cause reflex scratching or other measures to dispose of a collection of irritants. Itching can be overcome with scratch if this action could lift the material irritant or if scratching is considered strong enough to suppress itch signal propagation in the spinal cord by way of local lateral inhibition. Itching can be caused not only by repetitive local mechanical stimuli to the skin but also by various chemicals. There will be feeling a little itchy when the levels of bile salts in the plasma increases. Histamine causes severe itching, and the injury causes the release of histamine in the skin which can cause redness in the skin. Quinine group of compounds may also cause severe itching.
