The Stratum lucidum found only in a thick and hairless skin (e.g. Palm), it protects the underlying layer. The stratum corneum is the outermost layer in epidermis, it has a keratin and glycolipid to waterproof the skin and to avoid penetration and abrasion. The next layer in skin is dermis which the deep layer of skin and well-vascularized means that it has blood supply. Dermis has two distinct region: the Papillary and Reticular layer. Papillary layer is an upper dermal region which has projections called dermal papillae that responsible in fingerprint and capillary loops. Reticular the deepest layer in skin, it contains blood vessels, collagen fibers that gives skin toughness and elastic fiber for …show more content…
Our skin helps to control body temperature known as thermoregulation. The thermoregulation as one of the process in homeostasis that both of skin and hypothalamus receptor are involved. The hypothalamus will send a signals in skin which of the Krause (hot) or Ruffini (cold) are appropriately activated , and sweat glands is activated to release sweat so that the temperature in the body will appropriately response back to normal either decreasing or increasing. The sensitivity in our skin is because of the receptor including pain and touch. One of the human sense has is the touch or somatosensory system. The pacinian corpuscle serve as a largest touch sensor found in a third layer of skin, the hypodermis and meissner’s corpuscle activated for light toucf . Also the nociceptor is in ivolved it is responsible for detecting the
