SUPERFICIAL RECEPTORS OF SKIN ::
Skin consists of various types of sensory receptors These receptors are the nerve endings that receive the sensory impulses of touch pressure temperature pain itch etc Various nerve ending encapsulated in connective tissue of skin are Meissners corpuscles Pacinian corpuscle and krause s end bulb etc Meissners Corpuscles and Pacinian corpuscles are the mechanoreceptors that respond to touch or light pressure and deep pressure respectively Krauses end bulbs are thermoreceptors in skin which react to a decrease in temperature
In addition to above mentioned types of receptors there are naked nerve fibres These receptors respond to noxious or damaging stimuli such as excess pressure cuts and burns They are also termed as nociceptors They generate pain and hence are also known as algesireceptors
Some naked nerve endings mediate itch sensations which result from stimuli of low frequency that cause release of vasoactive peptides such as kinins or histamines
