YOUR ANSWER .....^_^___.
》IT TOOO LONG BUT I HAD GIVEN BECAUSE ITS VERY IMPORTANT PARA..N U ALSO SPEND MORE POINTS THATS WHY...
=¤》The skin is the most appropriate structure on which to hold a symposium. In a most real sense it is itself a symposium of structures, with correspondingly integrated functions. We may view the skin both its chemically and physically resistant epithelial surface and its tough fibrous dermal layer, as an envelope, a container for the bodily organs, chiefly dedicated to protecting these from physical, chemical and bacterial injury. INTO
■● THIS envelope the nervous system, an entirely separate tissue, has projected feelers, the sensory nerve endings, not so much to obtain information concerning the state of the skin as to explore the environment through and beyond it.
■●The skin as the intermediary between the nervous system and the environment then becomes itself the sense organ, and for pain endings we find no other specialized organ than the skin tissue surrounding the endings.
■●THESE are typically excited, short of skin damage, by bending sharply the epithelial layer; and through mechanical skin distortion, tension is put on nerve terminals.
□■FOR other sensory endings the skin has developed special containers for nerve endings whose function is to exclude certain forms of energy, as well as to transform others into nerve stimuli.
■□ THE skin, in other words, acts as a filter through which various forms of environmental energy are sorted out for the nervous system. The skin protects sense organs, as it protects other structures, against inappropriate influences.

the sensitivity of skin is based on the reflax action and reflex arc when our skin get an environmental stimulus the recepter present in skin send signal either to the cns wihich in turn commands the muscles to contarct and take a suitable action against stimulus or the change which happend with skin hope it helps you
