    • 1. Serous
    • 2. Synovial membrane
    • 3. Mucous membrane
    • 4. Cutaneous membrane or skin membranes are layers of skin that cover parts and line cavities of the body.
  2. serous peritoneum or peritoneal membrane
    lines the abdominopelvic cavity (peritonitis)
  3. Synovial membrane
    synovium lines joint cavity
  4. Mucous membrane
    Lines the vavities that open to the outside ex. mucousa of digestive tractm Mucosa of respiratory tract
  5. Cutaneous membrane or skin membranes
    layers of skin that cover parts and line cavities of the body.
  6. Glands are secretory components of the body. The secretions they produce are needed in another part of the body (DIA).
  7. Glands
    are secretory components of the body.
  8. Glands
    The secretions they produce are needed in another part of the body (DIA)
  9. There are two types of GLANDS
    Excocrine and Endocrine
  10. Exocrine Glands
    have a duct and secrete outside the body ex.: Breast Milk
  11. Endocrine Glands
    ductless grands that secrete inside the body through the blood vessels ex.:estrogen
  12. Facts about the skin
    • Largest organ of the body
    • Total surface area is 2sq meters or 300 sq inches
    • Skin is 15% of your total body weight
    • Varied thickness: eyelid skin - thinnest .02 mm, sole of foot 1.4 mm
    • Where the skin blends with the mucous membrane skin color is 'Ruddy'
  13. How many layers form the skin?
    Two layers, the epidermis and the dermis.
  14. Stratum
  15. Keratinization
    when the cells pass throught the stratum lucidum and Keratin protein is added to cell they becom resistant to water, chemicals, radiation and Microbes.
  16. Hair shaft
    Segment of the hair woutside the skin
  17. Hair root
    Segment of the hair within the skin
  18. Sebaceous gland
    Produces skin oil called sebum.
  19. Sebum
    Oil produced by the sebaceous gland that lubricates the hair as well as the skin
  20. Sebaceus glands secretions is controlled by the _________________ System
  21. The amount of secretion from the ______________ glands varies with
    age, puberty and pregnancy
  22. Hair follicle
    below the sebaceious gland, currounds the lower hair root
  23. Hair papilla
    produces the hair
  24. Pili Muscle or pilomotor muscle
    muscle at the side of the hair follicle the pulls the hair to stand in cold and when frightened
  25. Sudoriferous Glands
    Sweat Glands, Secrete sweat or perspiration, to cool the body and rids the body of waste through the pores. becomes odorous by the action of bacteria. The body looses o.5L of fluid per day through sweat
  26. Sudoriferous Glands
    3,000 sweat glands within 1 sq inch of the skin
  27. Sudoriferous Glands
    coiled, tubular glands, entire surface of the body except the lips, glans penis, and the inner surface of the prepuce.
  28. Apocrine
    Secretes "milky" sweat rich with organic substances situated in the armpit and anogenital area, rich with protein and carbohydrates
  29. Eccrine
    More widespread in the body, secretes watery sweat
  30. Skin cloration
    • I. Fleshy colotation of the skin is due to the color of the blood reflected throught the skin
    • II. Variation in skin coloration due to the concentration of the skin's dark brown pigment called melanin. Melanin is produced by the skin's pigment cells called melavocytes
  31. Cyanosis/cyanotic
    Having blush skin due to blood having deficient oxygent
  32. Jaundice
    Retention of Bilirubin makes skin yellowish. Millions of RBC's die normally every minute and they leave Bilirubin as residue. Body transports Bilirubin to the large intestine (makes feces yellow) and to the skin where white sun ray/light dissolves it. In Hemolytic disease. the skin can't cope in disposing Bilirubin and it turns yellow
  33. Erythema
    skin's redness due to increased blood supply as in sunburn, 1rst degree burn and blushing on the face.
