  1. What are tissues
    Groups of cells similar in structure and function
  2. what are the types of tissues
    • Epithelial tissue
    • Connective tissue
    • Muscle tissue
    • Nerve tissue
  3. the function of epithelial tissue is
    to protect the exposed portions of the body's organs and safeguard them from injury abrasion and injury.
  4. Where is epithelial tissues found
    on the surfaces of body organs
  5. the 1st type of epithelial tissue is
    simple squamous epithelium
  6. describe simple squamous epithelium
    • is a single layer of flat cells that lines the blood vessels, air sacs of the lungs, and portions of the kidney...
    • it is attached to a basement membrane...
    • the nucleus is at the center of the cells...
    • in the heart & blood vessels it is called endothelium while in the abdominal cavities its called mesothelium....
  7. what is the function of simple squamous epithelium
    filter and exchange
  8. what is the 2nd type of epithelial tissue
    simple cuboidal
  9. what is the function simple cuboidal epithelium
    it secretes various substances and is used for protection
  10. describe simple cuboidal epithelial
    single layered of cubed-shaped cells found in the kidney tubules and many excretory glands
  11. what is the 3rd epithelial tissue
    simple columnar epithelium
  12. describe simple columnar epithelium
    found in the gastrointestinal tract from stomach to the anus and in ducts of many glands simple columnar epithelium is single layer of tall cylindrical cells with the nuclei occurring at the base of the cell
  13. Function and location of nervous tissue
    • Internal communication
    • Brain, spinal cord, and nervesImage Upload 1
  14. Function and location of muscle tissue
    • Contracts to cause movement
    • Muscles attached to bones (skeletal)
    • Muscles of heart (cardiac)
    • Muscles of walls of hollow organs (smooth)
    • Image Upload 2
  15. location and function of Epithelial tissue:
    • Forms boundaries between different environments, protects, secretes, absorbs, filters
    • Skin surface (epidermis)
    • Lining of GI tract organs
    • other hollow organs
    • Image Upload 3
  16. function and location of Connective tissue
    • Supports, protects, binds other tissues together
    • Bones Tendons
    • Fat and other soft padding tissue
    • Image Upload 4
  17. two main types of Epithelial Tissue (Epithelium) by location
    • 1.Covering and lining epitheliaOn external and internal surfaces
    • 2.Glandular epitheliaSecretory tissue in glands
  18. Characteristics of Epithelial Tissue Cont.
    • Cells have polarity—apical (upper, free) and basal (lower, attached) surfaces
    • Apical surfaces may bear microvilli (e.g., brush border of intestinal lining) or cilia (e.g., lining of trachea)
    • Non-cellular basal lamina of glycoprotein and collagen lies adjacent to basal surface
  19. Classification of Epithelia Ask two questions
    • 1.How many layers? 1 = simple epithelium
    • >1 = stratified epithelium
    • 2.What type of cell? Squamous Cuboidal Columnar –(If stratified, name according to apical layer of cells
