  1. levels of organization
    • 1. cells
    • 2. tissues
    • 3. organs
    • 4. systems
    • 5. organisms
  2. cells are microscopic
    measured in micrometers, 10-6 meters
  3. anatomical descriptions are based on the "anatomical position"
    • (also called "supine position" when laying flat)
    • Image Upload 2
  4. planes of reference
    saggital: left-right

    coronal: front-back

    transverse: top-bottom

  5. directional descriptions
    anterior-posterior
    superior-inferior
    medial-lateral
    proximal-distal

  6. hypertrophy
    increase in cell size
  7. hyperplasia
    increase in number of cells
  8. atrophy
    decrease in cell size
  9. metaplasia
    change in cells shape
  10. tissues
    • -Groups of similar cells with a common function.
    • -Tissues are precise organizations of similar cells that perform specialized functions.
  11. histology
    microscopic anatomy
  12. all basic tissues and organs are derived from these 3 basic embryonic germ layers
    • 1. ectoderm
    • 2. mesoderm
    • 3. endoderm
  13. these steps happen prior to implantation in the uterus
    zygote - morula - blastula... then inner cells mass forms embryonic disc.. which forms the 3 germ layers 1. ectoderm 2. mesoderm 3. endoderm
  14. 4 basic kinds of tissue
    • -epithelium
    • -connective tissue
    • -muscle
    • -nerve
