  1. 3 means of communication in the body
    • nervous system
    • circulation system
    • lymphatic system
  2. homeostasis
    nervous and endocrine systems
  3. nervous system serves 3 functions
    • sensory
    • integrative
    • motor
  4. neuron
    fundamental unit of all branches and divisions of nervous system
  5. somatic
    muscle

    visceral: organs
  6. nerve endings
    telodendra
  7. mylinated 
    • shwann cells (in peripheral nerves)
    • oligodendrocytes (CNS)
  8. the most basic impulse conduction system, simple reflex (reflex arc) is composed of:
    • receptor
    • sensory neuron
    • association neuron
    • motor neuron
    • effector
  9. portion of PNS that controls unconscious body activities or visceral organs
    autonomic nervous system
  10. ANS controls involuntary, visceral functions such as:
    • GI motility
    • rate&force of heart beat
    • secretion of glands
    • pupil size
  11. two subdivisions of ANS
    • sympathetic
    • parasympathetic
  12. cholinergic
    parasympathetic
  13. adrenergic
    sympathetic 
  14. sympathetic regulates
    • energy-expending activities
    • "fight or flight"
  15. parasympathetic regulates
    • energy-conserving activities
    • "digestion"
  16. spinal innervation, think:
    somatic/muscle
  17. autonomic innervation, think:
    visceral
  18. adrenal medulla, sweat glands, and hair follicles have only what type of fibers?
    sympathetic
  19. stimulation of sympathetic system
    • increased HR
    • dilation of bronchioles
    • increased respiratory
    • decrease GI activity
    • dilated pupils
    • constriction of smooth muscle blood vessels
    • dilation of skeletal muscle blood vessels
    • increase blood glucose
  20. receptors of sympathetic (adrenergic)
    • alpha 1
    • alpha 2
    • beta 1
    • beta 2
    • dopaminergic 
  21. primary neurotransmitters of adrenergic sites
    • Norepinephrine
    • Epinephrine
    • L-Dopa
    • Dopamine
  22. why is epinephrine used to revive patients?
    stimulates alpha&beta receptors equally (therefore, potent stimulator of the heart and dilator of bronchioles)
