5 Matching Questions

  1. equilbrium potentials
  2. 2 ways to increas ap propagation
  3. relative refractory period
  4. sympathetic system
  5. neurotransmitters classes
  1. a - ends when K channel closes
    - a stimulus can excite an ap, but it must be stronger than the minimum stimulus required to elict an ap at rest
  2. b - ANS
    - innervates all organs, glands, and smooth muscles
    - always active, under the influence of hypothalamus to maitian homeostasis
    - readies body for action, increase heart rate, bp, moves blood to muscles away from viscera
    - fear; neurons in hypothalamus and brain stem activate adrenal glands that secrete adrenalin aka epinephrine
  3. c - large changes in Vm
    - net difference in electrical charges
    - rate of movement of ions across the memebrane
    - concenetration difference; equilbrium potential can be calculated
  4. d - amine, "-ine" or "-in"
    - amino acids, starts with "g" & aspartate
    - peptides, everything else
  5. e 1. increase internal diameter of axons which decreases the internal resistance to ion flow
    2. increase the resistance of the plasma membrane to charge flow by insulating it with myelin

5 Multiple Choice Questions

  1. - the ability of plasma membrane to store or seperate cherges of opposite signs
  2. - ap travels in one direction
  3. - calculate membrane potential
  4. 1. AP comes to axon terminus & causes depolarization
    2. depolarization opens up Ca2+ channels
    3. Ca2+ binds to SNARE proteins (esp. synaptotgmin)
    4. vessicle membrane & axon membrane fuse together
    5. exocytosis of NT-bind receptors
    6. vessicle membrane is recycled
    -> via clathin mediated endocytosis and
    -> dynamin for hydrolysis of GTP (energy for recycling)
  5. - main output nerons from cerebellum into spinal cord to innervate motor neurons in ventral horn
    - emoboliform
    - denate
    - globose
    - fastigial

5 True/False Questions

  1. push pull method- different g proteins or stimulate annd inhibit adenylyl cyclase
    - causes formation of cAMP and activation of PKA
    - PKA phosphorylates serine & threonine residues on target proteins

          

  2. neuronal integration- time constant
    - time it takes for a constant applied voltage to build up to 63 % of final value

          

  3. primary somatosensory cortex- in partietal lobe, posterior to central sulcus
    - carriers on higher order processing of sensory info
    - receives synaptic input from vp nucleus of thalamus
    - respond to somatosensory info
    - thalamic input it to cortical layer IV which sends axons to other layers in the same area
    - reciprocal (bidirectional) connections between cortical areas & association pathways

          

  4. inhibitory transmission1. AP comes to axon terminus & causes depolarization
    2. depolarization opens up Ca2+ channels
    3. Ca2+ binds to SNARE proteins (esp. synaptotgmin)
    4. vessicle membrane & axon membrane fuse together
    5. exocytosis of NT-bind receptors
    6. vessicle membrane is recycled
    -> via clathin mediated endocytosis and
    -> dynamin for hydrolysis of GTP (energy for recycling)

          

  5. exocytosis- depolarization of the post-synaptic membrane caused by the neurotransmitter brings the membrane potential close to the threshold for firing an ap
    - influx of Na or Ca
