A&P Terminology

  1. topographic
    study of parts in their relation to surrounding parts (mapping things out) how things are related to neighboring parts
  2. homologic
    study of related parts of the body with different animals
  3. comparative
    comparing of the different structures of different animals and plants with another
  4. clinical
    clinical practice (nursing, pt, ot)
  5. environmental physiology
    how we respond to environment (mining, space, high elevation..)
  6. evolutionary physiology
    how we change over generations
  7. comparative physiology
    diversity of various organisms
  8. sports physiology
    function during sport
  9. exercise physiology
    function of body during exercise
  10. organ physiology
    specific organs in the body
  11. radiographic
    study via x-ray
  12. homeostasis
    • maintanence of a relatively stable internal environment despite continuous outsie changes
    • survivial: nutrition, oxygen, water, body temp, atmospheric pressure
  13. homeostatic imbalance
    • disturbance of homeostasis
    • increases risk of disease
    • contributes to changes associated with aging
    • may allow destructive positive feedback mechanisms to take over (heart failure)
  14. positive feedback
    • the response enhances or exaggerates the original stimulus
    • one system speeds up (stimulates) another system to go faster
    • may exhibit cascade or amplifying effect ex. oxytocin
    • enhancement of labor contractions by oxytocin
    • platelet plug formation and blood clotting
  15. negative feedback
    output of a system opposes changes to the input of another system

    • ex. regulation of blood volume by ADH (antidiuretic hormone)
    • receptors sense decreased blood volume
    • control center in hypothalamus stimulates pitituary gland to release ADH
    • ADH causes kidneys (effectors) to return more water to the blood
