  1. Deffine Anatomy
    ivestigates the body' structure
  2. Define physiology
    investigates the processes or functions of living things
  3. Name in order the 6 levels of functional organization
    • 1) Chemical
    • 2) Cell
    • 3) Tissue
    • 4) Organ
    • 5) Organ system
    • 6) organism
  4. Define the chemical level
    Interaction of atoms
  5. define the cell level
    structural and functional unit of all living organisms
  6. define the tissue level
    group of similar cells and the materials surrounding them
  7. define the organ level
    one or more tissues functtioning together
  8. define the organ system level
    group of organs functioning together
  9. Define an organsim
    any living thing
  10. List the 6 characteristics of life
    • 1) Organization
    • 2) Metabolism
    • 3) Responsiveness
    • 4) Growth
    • 5) Development
    • 6) Reproduction
  11. Define organization
    condition in which there are specific relationships and functions
  12. define metabolism
    all chemical reactions of the body
  13. define responsiveness
    ability to sense changes and adjust
  14. define growth
    increase in size and/or number of cells
  15. define development
    changes in an organism over time
  16. define differentiation
    changes from general to specific
  17. define morphogenesis
    changes in shape of tissue/ organs
  18. define reproduction
    new cells or organisms
  19. define median
    through the midline
  20. define saggital
    to the left or the right of the midline
  21. define frontal
    divides the body into posterior and anterior sections
  22. define transverse
    divides the body in superior and inferior sections
  23. define oblique
    other than a right angle
  24. define homeostasis
    ability to maintain relatively stable internal conditions even though the outside world changes continuously
  25. list step 1 in the homestasis cyle
    11. stimulus produces change in variable
  26. list step 2 in the homeostasis cycle
    2. changed detected by receptor
  27. list step 3 in the homeostasis cycle
    Input: information sent along afferent pathway to control center
  28. list step 4 in the homeostasis cycle
    4. Output: information is sent along the efferent pathway to the effector
  29. list step 5 in the homeostasis cycle
    5. Response: effector feeds back to influence magnitude of stimulus and returns varible back to homeostasis
  30. define positive feedback
    the result or response enhances the original stimulus so that the output is accelerated
  31. define negative feedback
    the output shuts off the original stimulus or reduces it's intensity
  32. give and example of positive feedback in homeostasis
    the release of oxytocin to cause uterine contractions during labour
  33. give an example of negative feedbaxk in homeostasis
    the regulation of bdy temperature
