1. After an action potential arrives at the synapse, the of triggers the
fusion of synaptic vesicles with the membrane: influx, calcium
2. The synaptic vesicle fuses to the cell's membrane by the action of the
protein complex, releasing neurotransmitter into the : SNARE, synaptic clef
3. When an AP arrives at the terminal, the voltage-gated channels are
opened on the terminal: presynaptic, calcium, presynaptic
4. Botulism is a potentially lethal infection. What is the most probable con-
sequence of botox injections at the neuromuscular junction?: The vesticular
fusion does not function properly decreasing acetylcholine release
5. Dr. Matt Walters, accidentally injects himself with dynasore. What symp-
tom?: Muscle weakness because less neurotransmitter is released due to less
vesicle availability
6. An AP may result in release of all the following into the synaptic cleft
except: calcium molecules
7. Which proteins are found in very high concentrations on synaptic vesicles?-
: V-snares
8. Neostigmine- how does improve muscle weakness?: It causes Ach to stay in
the synaptic cleft for a longer amount of time
9. What is the force that brings neurotransmitters from the presynaptic cleft
to the postsynaptic side?: diffusion
10. Chemical communication in the nervous system depends on all of the
following except: if the neuron is myelinated or unmyelinated
11. What is not part of the four main criteria to be considered a neurotransmit-
ter?: A mechanism can not exist for removing the chemical from its site of activation
after its work is done
1/6
, 12. Electrical synapses have advantages over chemical synapses because of
their: speed of signal
13. Which pool of vesicles fuse with the cell's membrane during neurotrans-
mitter release?: readily-releasable pool
14. The decision of a neuron within a circuit to send an AP is dependent on all
of the following except: the speed of the AP in the presynaptic neuron
15. In comparison to excitatory inputs, inhibitory inputs are thought to occur
mainly close to the: cell body
16. Which of the following statements accurately describes convergence?: It
occurs when multiple, potentially disparate inputs come together to synapse onto a
single downstream neuron
17. Neuron A vs B, A synapses at dendrite, B synapses at cell body: Neuron B
has control
18. In the CNS, excitatory postsynaptic potentials are largely due to: glutamate
