Epidermis	Dermis	Sweat Glands	Oil Glands	Skin Functions, Cancers, and Burns
100 Epidermis What is the most superficial layer of the skin called?	100 epidermis The dermis sits below the ______	100 ECCRINE sweat glands, and APOCRINE sweat glands What are the two different types of sweat glands?	100 Sebaceous gland What is another name for oil glands?	100 Our skin has naturally low pH to slow bacteria multiplication What is the acid mantle?
200 4!! Keratinocytes, Melanocytes, Dendritic cells, tactile cells How many types of cells can you find in the epidermis? What are they?	200 Fibroblasts, macrophages, occasionally mast cells and white blood cells What cells are found in the dermis?	200 eccrine, apocrine _______ glands secrete mostly water, while _______- glands secrete viscous milk or yellowish sweat	200 Puberty When do oil glands begin to secrete sebum?	200 Chemical barriers - skin secretes chemicals for defense against unwanted bacteria Physical - flat dead keratinocytes with glycolipids to block water from entering and exiting without control Biological - immune response, dendritic cells engulf bacteria and calls the immune system What are the three barriers of protection for the skin? What are some characteristics of them?
300 stratum lucidum Which layer of the epidermis is ONLY found in thick skin?	300 Papillary (more superficial) and reticular What are the two layers of the dermis? Which is more superficial?	300 Eccrine, most numerous, in your palms, soles of feet and forehead, function : thermoregulation by sympathetic NS (fight or flight), attached directly to the pore/duct What are some characteristics of eccrine glands?	300 oil, blackheads Whiteheads are blocked ______ glands, if secretion is oxidized whiteheads become _________	300 Protection, body temperature regulation, cutaneous sensations, metabolic functions, blood reservoir, excretion of wastes What are the six functions of skin?
400 Stratum basale, spinosum, granulosum, lucidum, corneum What are the 5 layers of the epidermis in order from deepest to most superficial	400 Superficial region of dermis, projecting upward into dermis, where you find blood supply the epidermis relies on. Carries blood supply and free nerve endings, helps us know when and where we are being touched. What are friction ridges? What is the function of friction ridges?	400 Apocrine in axillary and anogenital areas, larger gland, unknown function, maybe sexual scent gland What are some characteristics of apocrine glands?	400 pores/hair duct Where do oil glands secrete directly into?	400 Basal cell carcinoma = least malignant,LEAST HARMFUL of the three, most common Squamous cell carcinoma = second most common, can spread from where it is originally Melanoma = cancer of the melanocytes (produces melanin- skin pigment, protects us from UV rays), most dangerous bc highly spreadable (malignant) and resistant to chemotherapy What are the three major types of skin cancer? What are some of the qualities of each?
500 . Melanocytes : produces melanin, protects against UV rays, Dendritic cells : macrophage-like, key indicator of immune system. Tactile Cells : sensory receptors Give a description of every cell found in the epidermis (keratinocytes, dendritic cells, melanocytes, tactile cells)	500 Elastic fibers = provide stretch-recoil properties (you can pull your skin away from your face but when you let it go it will return back to original shape). Collagen fibers = provide strength and resiliency What two fibers are found in abundance in the reticular layer? What is the function of those?	500 Ceruminous = secrete cerumen (earwax), Mammary glands = secrete milk What are the two types of modified apocrine sweat glands and what do they secrete?	500 secretes sebum to soften hair and skin Helps prevent water loss has bacterial killing properties What are the three functions of oil glands?	500 1st degree = Epidermal damage only, localized redness, swelling and pain 2nd degree = Epidermal and upper dermal damage, blisters appear (irritation between dermis and epidermis) 3rd degree = Entire thickness of skin involved, referred to as full-thickness burns, skin color turns gray-white, cherry read, or blackened, no swelling, and area is not as painful because nerve endings are destroyed, skin grafting usually necessary How can you tell the difference between a 1st, 2nd, and 3rd degree burn?
