Homeostasis, bod planes
Show Answers:

  1. Homeostasis
    ability to maintain a relatively constant internal environment in the body
  2. Two mechanisms for maintaing homeostasis
    • Negative feed back loop
    • *immediately reverses the situation to restore homeostasis
    • ^ ex. blood pressure or body temp
    • Positive feed back loop
    • *must first intensify the situation to restore homeostasis
    • ^ ex. child birth
  3. Feed back loops
    Keep the body aware of any changes and also attemps to correct the situation to restore homeostasis
  4. Factors involved in a feed back loop
    • Normal controlled condition
    • Receptor
    • Control Center
    • Effector
  5. Molecules
    • are made of an element that retian the elements physical and chemical properties.
    • These bond together to form molecules.
  6. Compounds
    are also made of atoms that are bonded together but, it must be two or more different atoms
  7. Atoms
    the smallest units of an element that retain the elements physical and chemical properties. These bond together to form molecules.
  8. Subatomic Particles
    protons, neutrons, electrons
  9. Elements
    the basic building blocks of matter that cannot be broken down by chemical means
  10. Matter
    anything that has weight and takes up space
  11. How are cells organized?
    • muscle cell
    • muscle tissue
    • organ
    • organ system organism
  12. Anatomy from the patients perspective
    ALWAYS there left and right NOT yours!
  13. Superior
  14. Inferior
  15. Ventral
    in front of

  17. Intermediate
    between a more medical and a more lateral structure
  18. Proximal
    closer to the orgin of the body part or the point of attachment of a limb to the body trunk
  19. Distal
    farther from the orgin of a body part or the point of attachment of a limb to the body trunk
  20. Superficial
    Toward or at the body surface
  21. Deep
    Away from the body surface; more internal
