  28. xer/o

  29. -derma
    skin
  30. -opsy

  31. -tome
    instrument for cutting
  32. allo-
    other; different from usual
  33. xeno-
    strange; foreign
  34. organs of the integumentary system:
    • nails
    • sweat glands
    • sebacious glands
    • hair
    • skin
  35. cutaneous membrane
    skin
  36. primary functions of skin
    • protection against pathogens and chemicals
    • protection of organs and fluids inside body
    • temp regulation (sweat, blood vessel contraction/dilation, fat layer)
  37. sensory receptors:
    in the skin, detect pain, temp, touch and pressure and convey messages to the spinal cord and brain
  38. sebacious glands
    oil glands that produce lubrication for the skin
  39. epidermis
    thin, outer membrane of skin with no blood supply or connective tissue
  40. dermis
    • middle, fibrous, connective tissue layer of skin
    • aka: corium
    • living tissue with good blood supply
  41. subcutaneous layer
    • innermost layer of skin containing fatty tissue
    • aka: hypodermis
    • composed of fat cells (lipocytes)
  42. stratified squamous epithelium
    flat, scale like cells arranged in overlapping layers which compose the epidermis
  43. basal layer
    • deepest layer of epidermis
    • new cells in formed here push older hardened cells to surface
  44. melanocytes
    cells loc'd in the basal layer which contain the skins pigment, melanin
  45. keratin
    hard protein substance found in hair, nails and inside of epidermal cells
  46. collagen fibers
    made of strong, fibrous protien which forms the "glue" that makes connective tissue strong
  47. 8 things found in the dermis:
    • hair follicles
    • sweat glands
    • sebacious glands
    • blood vessels
    • lymph vessels
    • sensory receptors
    • nerve fibers
    • muscle fibers
  48. epidermal-dermal junction
    • specialized area btwn 2 primary skin layers
    • blisters are caused when there is a disconnect at this junction
  49. hair follicles
    tube like structure under surface of skin where hair root is found
  50. hair shaft
    visible part of hair above skin surface
  51. sebacious glands in hair release oil into:
    hair follicle
  52. meissners corpuscle
    detect light touch to skin
  53. pacinian corpuscle
    detects pressure to skin
  54. arrector pili
    • smooth slip of muscle attached to each hair
    • when contracted, hair shaft stands up (goose bumps)
  55. nail body
    flat plate of keratin that forms visible part of finger/toe nails
  56. nail bed
    connective tissue that connects the nail body to the tissue underneath
