Document Summary
Immune response coordination to pathogens and cancers in the skin. Composed of stratified squamous epithelium (several layers of flat epithelial cells) Sensory receptors detect touch, pressure, pain and temperature. 4 different cell types: keratinocytes - contributes to skin thickening and toughening, melanocytes - contributes to melanin (skin pigment, merkel cells - help with sensation, langerhans cells - immune response. Thick skin is found at the soles of the feet and the palms (thin skin for the remainder) Thin skin has 4 layers, the thick skin has 1 extra layer (5 layers including the stratum lucidum, Langerhans cells found in the stratum spinosum. Keratinocytes present within all layers except the stratum lucidum and basale which is only found in thick skin ) *remember these in their correct order of sequence for potential exam questions ( c an luci. G ive s ome b lood) of connective tissue with many adipocytes )
