5 Matching questions

  1. goldman equation
  2. S1 cortex restriction of information
  3. axon hillick
  4. basal ganglie-striatum
  5. scale tympani
  1. a - used to calculate membrane potential
    - assumes that electrical field of the membrane potential is equal across the span of the membrane
  2. b - 3 fore brain nuclei involved in motor control
    - putamen
    - globus pallidus
    - caudate nucleus
  3. c - beginning of axon
    - influenced sesnsitivity by shunting inhihibtion; inhibiting current flow from soma to axon hillock
  4. d - compartment connected to round window
    - has perilymph fluid
  5. e - some cortex areas specialize in decoding texture, shape, and size

5 Multiple choice questions

  1. - injury caused
    - do not recognize body part as your own
    - do not dress it or wash it
  2. - chemical nature of nerve transmission
    - proved that some soluble chemical released by the vagus nerve was controlling the heart rate
  3. - ap travels in one direction
  4. - a drug or compund that inhibits the action of the naturally occuring NT
  5. - ANS
    - innervate all organs except liver, skin & arteries
    - always active to maintain homeostasis
    - causes relaxation & ihibits activity of innverated end organs
    - except increases digestion
    - bp, hr decrease, blood flow directed from muscle to viscera

5 True/False questions

  1. catecholamines- a pressure wave reaches the oval window and pushes it inward and increases pressure above the basilar membrane
    - basilar membrane moves downward as pressure is released by bulging out of the round window at base of cochlea
    - 3 components
    1. scala vestibuli
    2. sale tympani
    - scala media


  2. exocytosis- a calcium dependent process
    - membrane bound individual vesicles fuse with the plasma membrane
    - spill the intracellular contents of the vesicle into the extracellular space, referred to as the synaptic cleft


  3. motor neurons- innervates muscle
    - soma is in the ventral horn grey matter of the spinal cord at each level
    - efferent


  4. synaptotagmin- needed for vesicle exocytosis
    - binds to voltage sensitive calcium channel so that it is physically close to the two opposing membranes that will fuse after synaptotagmin binds calcium


  5. sensory neurons- innervates muscle
    - soma is in the ventral horn grey matter of the spinal cord at each level
    - efferent
