  • 1

    Where is Epithelium tissue

    Cover body surfaces, cover and line organs

  • 2

    Epithelial classifications

    Simple squamous Simple cuboidal Simple columnar Pseudostratified columnar Stratified squamous Stratified cuboidal Transitional

  • 3

    Simple squamous epithelium

    Definition: single layer of flat cells with disc-shaped nuclei and little cytoplasm Function: allows easy passage of materials and helps organs move smoothly Location: kidneys, lungs, the heart lining, blood vessels, lymph vessels, and body cavities.

  • 4

    Simple cuboidal epithelium

    Description: single layer of cubelike cells with large, round central nuclei Function: Secretion and absorption Location: Kidney tubules,ducts and ovary surface

  • 5

    Simple columnar epithelium

    Description: single layer of tall cells with round to oval nuclei, some have microvilli; nucleus located near basement membrane Function: absorption, secretion, protection Location: linings of the uterus, stomach, and intestine

  • 6

    Pseudostratified columnar epithelium

    Description: single layer of cells that appears multilayered due to nuclei at varying levels Function: protection, secretion, movement of mucus. Location: trachea Nonciliated type in male urethra

  • 7

    Surface of epithelium tissues

    Apical surface (Outer surface) Basal surface (Inner surface)

  • 8

    Features of Apical Surface

    Microvilli: in small intestine Cilia: in Trachea (Kartagener syndrome = immobile cilia syndrome) Goblet cells produce mucus: gland cell, modified simple columnar epithelial cell

  • 9

    Cytoskeleton protein

    Actin filament Intermediate filament Microtubule

  • 10

    Stratified squamous epithelium

    Description: multiple layers of flattened cells Location: • Kertinized forms epidermis of the skin • Nonkeratinized forms the moist linings of esophagus, mouth,and vagina Function: protection

  • 11

    Nonkeratinized Stratified Squamous

    Description: Multilayered epithelium that has no dead cells forming moist, slippery layer Locations: tongue, oral mucosa, esophagus & vagina Function: Protects wet surfaces

  • 12

    Stratified cuboidal epithelium

    Description: 2 or 3 layers of cuboidal cells Location: linings of larger ducts of mammary glands, sweat glands, salivary glands,and pancreas Function: protection

  • 13

    Stratified columnar epithelium

    Description: 2 or 3 layers of cells of columnar cells Location: eye lining, eyelids, vas deferens, part of male urethra, parts of throat Function: protection and mucus secreting

  • 14

    Transitional epithelium

    Description: stretch Location: Inner lining of urinary bladder and linings of the ureters and part of urethra Function: protection

  • 15

    Epithelial Tissues Characteristics

    Tightly packed No blood vessels Basement membrane anchors epithelium to connective tissue Exposed surface

  • 16

    Tight junction

    Controls what get in

  • 17

    Anchoring Junction

    Desmosome: connect cells and reduce tissue tension Zonula adherens: glue cells together

  • 18
