Questions in this quiz (9)

  1. 1Acetyl Choline always produces an EPSP.
    1. ATrue
    2. BFalse
  2. 2Glutamate produces an IPSP.
    1. ATrue
    2. BFalse
  3. 3Gaba produces an IPSP.
    1. ATrue
    2. BFalse
  4. 4Choose the correct statements about methamphetamine.
    1. AIt increases levels of noradrenaline, dopamine, and serotonin.
    2. BIt blocks the reuptake of noradrenaline, dopamine, and serotonin.
    3. CIt acts in reward centres and as such is highly addictive.
    4. DIt stimulates the parasympathetic nervous system.
  5. 5Choose the incorrect statement.
    1. AAcetylcholine activates stimulus gated Na+ channels, and can be found in NMJs and the brain.
    2. BGlutamate activates stimulus gated Na+ and Ca+ channels, and is the most common excitatory neurotransmitter in the CNS.
    3. CGABA activates Na+ and Cl- channels, and is the most common inhibitory neurotransmitter in the CNS.
  6. 6A neuron can have >50,000 synapses at its input zone.
    1. ATrue
    2. BFalse
  7. 7Local synaptic potential (EPSPs and IPSPs) summate.
    Spatial summation is integration of inputs from [blank_start]different synaptic knobs[blank_end]. (Different localisation/[blank_start]local polarisations[blank_end] of input zone.)
    Temporal summation is the integration of inputs from the [blank_start]same synaptic knob[blank_end] but from different, [blank_start]short time intervals[blank_end].
    1. Adifferent synaptic knobs
    2. Blocal polarisations
    3. Csame synaptic knob
    4. Dshort time intervals
  8. 8Local polarisations last longer than action potentials. This allows temporal summation to be effective.
    1. ATrue
    2. BFalse
  9. 9Converging networks can amplify signals. They have few control points and can therefore allow precise control.
    Diverging networks provide redundancy, making sure there is a 'back up' should another transmission fail and assuring an action is carried out.
    1. ATrue
    2. BFalse
