  1. Mineral corticoids
    • Particularly aldosterone---regulate plasma K+ and Na+
    • increase aldosterone reabsorption of Na+ and passive reabsorption of water in the nephron. This increases blood volume and blood pressure
    • secreted by adrenal cortex
  2. Saprophytic
    • decompose dead organic matter
    • most bacteria and fungi (ringworm) are saprophytic
  3. Universal blood recipient
    Type AB---has neither anti-A nor anti B antibodies
  4. Primer Pheramones
    • produce long-term behavioral and physiological alterations in recipient
    • Ex. pheromones of male mice affect estrogen cycles of females
  5. Neurotransmitter removed in one of two ways
    • taken back up into the nerve terminal via a protein called an uptake carrier
    • degradeded by enzymes in the synpase (acetylcholinesterase...inactivity acetylcholme)
    • diffuse out of synapse
  6. Intertidal Zone
    region exposed at low tides
  7. Aqueous Humor
    • fills area between lens and cornea
    • exits through ducts to join veneous blood
  8. Glaucoma
    increase of pressure in eye due to blockage of aqueous humor outflow
  9. Artery Properties
    thickwalled, muscular, elastic
  10. vein properties
    thin walled inelastic
  11. Aneuploidy (the result of..?)
    • abnormal chromosome #
    • can occur by nondisjunction of homologous chromosomes during meiosis, or nondisjunction of sister chromatids during meiosis II
  12. Erythrocytes
    How formed/terminated
    • formed: from stem cells in the bone marrow have lost nuclei, mitoch and membranous organelles
    • termination: after 120 are phagocytized by cells in spleen and liver
  13. Macrophages
    • type of WBC that has migrated from blood to tissue where mature into stationary cells
    • engulf and destroy cells
  14. the Egg: Chorion
    lines the inside of shell. Moist membrane that permits gas exchange
  15. Pituitary gland
    the pituitary (hypophysis) consists of anterior and posterior lobes
  16. Autonomic Nervous System
    • Involuntary nervous system that regulates body's internal environment
    • composed of sympathetic and parasympathetic nervous systems.
  17. Origin
    Point of attachment of a muscle to a stationary bone (proximal end of limb muscles)
  18. Rh factor
    • another antigen on RBC
    • Rh+ possesses antigen
    • Rh- is lacking

    Ex. Rh- woman is sensitized to Rh+ RBC's of fetus. For next Rh+ child will produce antibodies that destroy fetal RBC's resulting in erythroblastosis fetalis (anemia)
  19. Invertabrate NV: Protozoa
    • No organized nervous system
    • may respond to touch heat, light, chemicals
  20. Tendons
    attach skeletal muscle to bones and bend the skeleton at movable joints
  21. Sclera
    white part of the eye
  22. Repressible Systems
    are in a constant state of transcription (repressor is inactive) unless a corepressor is present to inhibit
  23. Osteoclasts
    • large, multinucleated
    • bone resorption
