    1. AUnipolar
    2. BPseudounipolar
    3. CBipolar
    4. DMultipolar
  3. 3What is the resting potential in a neuron?
    1. A-90mv
    2. B-80mv
    3. C-70mv
  4. 4The upstroke of the neuron action potential is mediated by voltage gated [blank_start]Sodium[blank_end] channels
    The downstroke is then mediated by voltage gated [blank_start]Potassium[blank_end] channels
    1. ASodium
    2. BPotassium
    3. CCalcium
    4. DPotassium
    5. ECalcium
    6. FSodium
  5. 5Saltatory conduction describes the way in which action potential jump from one [blank_start]Node of Ranvier[blank_end] to the next
    1. ANode of Ranvier
  6. 6The release of the neurotransmitter in a synapse at the end of a neuron is mediated by which type of channel?
    1. ACalcium channel
    2. BSodium channel
    3. CPotassium channel
  7. 7The part of the synapse that stores the neurotransmitter is called the [blank_start]vesicle[blank_end]
    1. Avesicle
  8. 8Types of Synapse:
    [blank_start]Axodendritic[blank_end] Synapse from axon to dendrite
    [blank_start]Axosomatic[blank_end] Synapse from axon the cell body
    [blank_start]Axoaxonic[blank_end] Synapse from axon to axon
    1. AAxodendritic
    2. BAxosomatic
    3. CAxoaxonic
  9. 9Synapses can be classified as excitatory or inhibitory.
    Excitatory synapses most frequently use the neurotransmitter [blank_start]glutamate[blank_end]
    Inhibitory synapses most frequently use the neurotransmitter [blank_start]GABA[blank_end]
    1. Aglutamate
    2. BGABA
  10. 10As well as GABA, what is the other main inhibitory neurotransmitter?
    [blank_start]Glycine[blank_end]
    1. AGlycine
