The flashcards below were created by user ChapinJeanie on FreezingBlue Flashcards. What would you like to do?


  1. The Skin
    • 1. Good Blood and Nerve¬†Supply
    • 2. Organ
    • 3. Deals with the Epithelial, Hair, Nails, Glands, oil
  2. The skins Main regions
    • 1.Epidermis
    • 2. Dermis
  3. The region Epidermis
    • 1. Stratified Squamous Epithelium
    • 2. No blood supply
  4. The Region of Dermis in the Skin
    • 1. Dense connective Tiusse
    • 2. Good blood supply
    • 3. Mypodermis is below the dermis (fat)
  5. Epidermis Cell types
    • 1. Keratinocytes
    • 2. Melanocytes
    • 3. Dendric Cells ( Langerhans Cells)
  6. Epidermis Cell Type
    Keratinocytes
    • 1. The majority of cells
    • 2. Always loosing because we flush away
    • 3. break layer could cause infection
  7. Epidermis Cell Type

    Melanocytes
    • 1. synthesize pigment melanin
    • 2. Melanin moves outside to Keratinocytes and spreads, becomes darker
    • 3. Ultraviolet light causes the cell to open up its DNA and prodce Melanin
  8. Epidermis CEll Type

    Dendritic Cells
    • 1. Langerhans cells
    • 2. Macrophage like cells that protect by phagocytosis
  9. Layers of the Epidermis
    Strat
  10. Layers of the Epidermis

    Forms of Skin
    • 1. Thick skin, over palms and heals 5 layers
    • 2. Thin skin, ove rmostof the body 4 layers
  11. Layers of Epidermis Strata
    • 1. Stratum corneum
    • 2. Stratum lucidum
    • 3. Stratum grandulosum
    • 4. Stratum spinosum
    • 5. Stratum basal
  12. Layers of the Epidermis

    Stratum Basal
    • 1. Deepest layer
    • 2. Single row of cells (Keratin and Melanin CYTES)
    • 3. more cell division, with division can come problems
  13. layers of the Epidermis

    Stratum Spinosum
    • 1. Spiny apperance
    • 2. Serval rows
    • 3. Keratinocytes and Langerhans cells (slow down cell division)
    • 4.CElls start to die after this layer
  14. Layers of Epidermis

    Stratum Grandulosum
    • 1. Grandular cytoplasm, grainy keratinocyte
    • 2. 2-3 rows
    • 3. KERATINIZATION begins here, see visable keratin cells
  15. Layers of Epidermis

    Stratym Lucidum
    • 1. Clear
    • 2. Few rows of flattened cells
    • 3. Callous
    • 4. THICK SKIN ONLY
  16. Layers of Epidermis

    Stratum corneum
    • 1. outtermost
    • 2. 20-30 rows
    • 3. cells filled with keratin
    • 4. DEAD
  17. Layers of Epidermis
    • 1. outtermost
    • 2. 20-30 rows
    • 3. cells filled with keratin
    • 4. DEAD
  18. Which is always made in the strata of Epidermis?
    Keratin NOT Melanin
  19. What is Dermis?
    Strong yet flexible skin layer
  20. What are the two layers in Dermis?
    • 1. Papillary layer
    • 2. Reticular layer
  21. Dermis layer Papillary
    • 1. areolar loose CT
    • 2. serface folded into ridgest (papillae)
    • 3. Finger print
    • 4. Good Blood supply and Nerve supply
  22. Layer of Dermins

    Reticular layer
    1. Dense irregular CT that impacts strength
  23. Skin color is due to?
    Pigment
  24. Skin color pigments
    • 1. Melanin
    • 2. Hemoglobin
    • 2. Carotene
  25. Skin color pigment

    Melanin
    1. amount and type related to skin color
  26. Skin color pigment

    Hemoglobin
    1. due to iron. Blood pigment
  27. Skin color pigment

    Carotene
    1. Yellowish pigment mostly in hypodermis
