  1. macrophages are_____ type of cell
    motile phagocytic cells
  2. find canaliculli, osteocytes, lacunae, central canal,
  3. 5 layers of epidermis
    • 1) stratum corneum
    • 2) stratum lucidium
    • 3) stratum granulosum
    • 4) stratum spinosum
    • 5)┬ástratum basale
  4. list 3 type of tissue that compose bone
    • 1) connective tissue
    • 2) osseous tissue
    • 3) nervous tissue
  5. 3 primary germ layers of embryonic tissue
    • 1) ecoderm (outer): nervous
    • 2) meoderm: mesenchyme (middle): membrane
    • 3) endoderm (inner)
  6. 3 functions of epithelial cells
    • 1) protection
    • 2) absorption/controm permeability.
    • 3) secretion
  7. 3 functions of connective tissue
    support, bind, protect
  8. list 2 types of nervous tissue
    neuroglia and neurons
  9. what are neurosomes
    houses nucleus and other organelles
  10. list 3 types of tissue growth
    • 1) hyperplasia: cell multiplication
    • 2) hypertrophy: cell enlargement
    • 3) neoplasia: tumor development
  11. methods of cell changing to other cells
    • 1) differentiation (e.g. mesenchyme to musscle)
    • 2) metaplasia (e.g. smoker pseudostratified columnar epithelium to simple squamous epithelium).
  12. methods for tissue repair
    • 1) regeneration: replacing dead w/same type.
    • 2) fibrosis: replacing damaged cells w/scar tissue
  13. types of tissue degeneration & death
    • 1) atrophy: shrinking tissue through lost cells.
    • 2) necrosis: premature cell death (e.g. gangrene, infarction)
    • 3) apoptosis: programmed cell death (phagocytized by macrophages)
  14. anatomical difference between secretion and excretion
    secretion=duct, excretion=no duct
