    10 characteristics of Epthelial tissue
  2. Simple Squamous Epithlium
  3. Tissue with flattened or scale-like cells, "squam" means scale, single layer of thin, flattened cells that fir together tightly, their nuclei are usually broad and thin diffusion (osmosis) and fitration readily occur through this tissue (eg air sacs fo lungs - oxygen and carbon dioxide exchanged here, walls of cappilaries, lining of blood vessels, and membranes that line body cavity) due to thinness, damage occurs easily.
    Simple Squamous Epithilium
  4. Simple cuboidal Epithium
  5. single layer of cube-shaped cells; nucleus large and centrally located; forms lingin of many glands and their ducts; found on surface of ovaries, inner surface of eye lens, piganeted epi. of eye retina, some kidney tubules with microvilli on cell surface; functions in secretion of mucus, sweat, enzymes and absorption of fluids.
    Simple Cuboidal Epithelium
  6. Simple Columnar Epithelium
  7. single layer of cells that are taller than they are wide; looks like simple cuboidal epi with elongated cells. Have large, oval-shaped nucleus, usually located at the base of the cells. may secrete mucus ( from goblet cells- the only unicellular glands in the human body maby have cilia or microvilli on free surface of cells, found in stomach lining, intestinal lining) digestive glands, gallbladder, fallopian tubes; functions in secretion, absorption, protection and lubrication; mucus and cilia combine to trap and sweep away foreign substances; cilia may also help to move objects through a duct.
    Simple Columnar Epithelium
  8. Stratisfied Squamous Epithelium Non keritanized
  9. several layers of cells; only superficial layer composed of flat squamous cells, underlying basal cells are modified cuboidal or columnar cells that are pushed upward from near basement membrane to replace dying superficial cells. shedding process in outer layer os called desquamation
    -occurs in areas where friction or possibilty of cellular injury or drying occurs (ie epidermis, vagina, mouth, esophagus anal canal, distal end of urethra.
    major function is protection, in skin replacement cells rising to the surface from underlying layers produce keratin
    their nuclei and organelles disappear and bt the time they reach the surface, they consist mostly of keratin; these keratinized cells flake off as the next batch fo cells reaches the surface.
    cells in a moist environment are non-kerantinized they retain their nuclei and organelles.
    Stratisfied Squamous Epithelium
  10. Pseudostratisfied Columnar Epithium
  11. single layer of cells of varying height and shape
    nuclei are different levels give false impression of multilayered structure
    all cells in contact with basement membrane, but not all reach superficial layer
    when ciliated, called pseudostratisfied ciliated columnar epithelium
    mainly located in larege excretory ducts, most of male reproductive tract, nasal cavity and other respiratory passages, and part of ear cavity
    major functions are protection, secretion, and movement of substances across surfaces; mucusfrom cells in respiratory tract traps foreign substances; mucus moved to throat by sweeping action of cilia and either coughed out or swallowed and later eliminated in feces.
