  1. Integumentary System Six-Protection, Sensation, Heat Control, Excretion, Vitamin and Hormone Manufacture, Absorption
  2. Skin Labels
    • 1. stratum corneum-the outer most layer made up of keratin filled cells
    • 2. stratum granulosum-the layer where it fills the skin cells with keratin
    • 3. stratum germinativum-the deepest epidermal layer responsible for cell division
    • 4. Meissner's corpuscle-nerve receptor responsible for the sensation of touch
    • 5. sebaceous gland-oil producing gland
    • 6. Pacinian corpuscle-nerve receptor which feels pressure and pain
    • 7. sudoriferous gland-sweat gland
    • 8. hair papilla-the region where the hair shaft grows from
    • 9. blood vessels-provides materials to the dermal layers and removes wastes from these regions
    • 10. hair follicle-the tube-like structure surrounding the hair shaft
    • 11. subcutaneous layer-the region beneath the dermis
    • 12. dermis-the deep layer of skin made up of dense connective tissue and skin accesories
    • 13. epidermis-the outer most layer of the skin made up of statified squamous epithelium
    • 14. erector pilli muscle-smooth muscles attached to hairs responsible for goose bumps
    • 15. hair shaft-a thread like structure produced within the hair follicle
    • 16. sweat pore-the ori fice by which sweat leaevs the duct
  3. Matching
    • acne-inflamation and blocking of a sebaceous gland
    • apocrine sweat gland-found in axilla and genitalie, produces a milky thick sweat
    • arrector pili-the muscle that errects hair follicles
    • blister-a breakdown and separation of the epidermal skin layers
    • bursa-fluid filled sacks found under tendons, lined with synovial fluid membrane
    • comedo-the inflamed plug that blocks sebaceous glands duct in acne
    • cutaneous-pertaining to skin
    • cuticle-the skin fold covering the root of a nail
    • cyanosis-the bluish tint of skin caused by oxygen deficiency in the blood
    • dehydration-excessive loss of body water
    • depilatories-hair removers
    • dermis-the deeper thicker layer of the skin with muscles,nerves, and hair papilla
    • eccrine sweat gland-the numerous sweat glands all over the body
    • epidermis-the outer layer of the skin
    • follicle-the tube from which hair grows
    • keratin-the protien substance in hair, nails and other skin cells
    • lanugo-body hair
    • lunula-the cressent shaped white area found under the proximal nail bed
    • Meissner's corpuscle-nerves capable of defecting light touch
    • melanin-brown skin pigment
    • melanocyte-a melanin producing cell
    • mucous membrane-a mucus producing membrane
    • mucus-the think secreation that keeps membranes soft and moist
    • pacinian corpuscle-the nerves capable of detecting pressure and pain
    • papilla-small nipple shapped elevations of the skin
    • parietal-the outer wall of an organ or cavity
    • peritoneum-the membrane lining of the abdomene pelvis cavity
    • peritonitis-inflimation of the periteneum
    • pleura-the membrane lining of the thoracic cavity
    • pleurisy-inflimation of the pleura
    • sebaceous gland-an oil producing gland of the skin oil sebum
    • serous-a membrane of squameous and loose connective tissue
    • stratum corneum-the outer most layer of keratin filled cells
    • subcutaneous-the loose connective tissue and fat found under the dermis
    • sudoriferous gland-a sweat producing gland
    • synovial-the eggwhite like fluid produced by the syovial membrane
    • viscernal-having to do with the internal organs
  4. Epidermis
    The outermost region of the skin produced by the stratum germinativum as cells are pushed up from that layer, they keratinize and eventually "flake off". This layer protects the tissues under it.
  5. Dermis
    the deeper layer of skin consisting of the skin accessories and connective tisse. This layer maintains the skin accessories.
  6. Burns
    • 1st-minor discomfort and reddening of the skin. damages the epidermal layers
    • 2nd-blisters, severe pain,swelling,fluid loss, and sometimes scarring. it damges epidermal and upper dermis layers
    • 3rd-severe scaning and nerve damage.epidermis and dermis destroyed, tissue death in the subcutaneous region
  7. Body Membranes
    • epithelial membranes:somposed of an outer later of epithelial tissue and an inner layer of conncetive tissue
    • conncetive tissue membrane:composed of two or more layers of connective tissue
  8. Epithelial Membranes
    • cutaneous-skin
    • serous-line the body cavities
    • mucous-line the tracts of the body:repiratory, digestive, urinary, and reproductive
  9. Examples of connective tissue membranes
    • synouial membranes, which line joints and bursa
    • adipose tissue membranes, which atore lipids
  10. Organs of the Skin
    • hair-grows from the papilla and becomes keratinized
    • arrector pili-smooth muscle that produces goose bumps
    • meissner's corpuscle-detects light touch
    • pacinian corpuscle-detects pressure
    • nails-enables dextarity
    • sudoriferous Glands-sweat glands
    • sebaceous glands-oil glands
  11. Skin Color
    Three reasons, the amount and size of the blood vessels near the skin surface, the amount of melanin produced by the melanocytes, and the color of the melanin:brown, black or yellow. Added sunlight which is exposed daily is the cause for our individual skin color
  12. Finger Prints
    The upper region of the dermis contains projections called dermal papilla, it is these projections that make fingerprints possible
