1 Section: Chapter 5: Multiple Choice 1. The structure of synapses is best viewed with a(n): p.155 electron microscope. light microscope. confocal microscope. nissle-stained microscopic procedure. 2. Electron microscopy is a useful tool in the study of synaptic morphology. The resolution of an electron microscope is much greater than that of a light microscope because: p.155 smaller electron waves scatter less than light waves. light waves scatter less than electron waves. larger electron waves scatter more than light waves. larger light waves scatter in similar patterns as electron waves. 3. The contents of a synaptic vesicle include: p.157 neurotransmitters. structural proteins. DNA. all of the above. 4. Which of the following are characteristic of the postsynaptic membrane? E. p.157 thickened appearance receptor proteins synaptic vesicles all of the above a and b 1

2 5. Precursor chemicals that form the building blocks for neurotransmitters are absorbed from the: p.158 mitochondria. blood. cell nucleus. Golgi apparatus. 6. Which of the following would not be found at the axon terminals? p.158 mitochondria cell membrane synaptic vesicles axon hillock 7. Voltage-gated calcium ion channels that function in neurotransmission are primarily found on the: p.159 postsynaptic membrane. presynaptic membrane. synaptic vesicles. dendrites. 8. Immediately before neurotransmission, calcium ions entering the presynaptic membrane bind to: p.159 calcitonin. calmodulin. calretenin. calpactin. 9. Synaptic vesicles release neurotransmitters through the process of: p.159 endocytosis. pinocytosis. exocytosis. phagocytosis. 2

E. membrane depolarization membrane hyperpolarization initiation of chemical reactions all of the above a and b only p For an action potential to be elicited: one quantum of neurotransmitter must be released from the presynaptic cell. multiple quanta of neurotransmitter must be released from the presynaptic cell. calcium ions must enter the postsynaptic cell. a and c. p How is a neurotransmitter removed from the synaptic cleft? E. diffusion enzymatic degradation uptake by surrounding glial cells all of the above a and b p Hormones are diffusely released to the rest of the body via: axodendritic synapses. axosomatic synapses. axosecretory synapses. axoaxonic synapses. p.161 3

4 14. Which of the following best characterizes type I and/or type II synapses? Type I synapses are excitatory and have round synaptic vesicles. Type II synapses are inhibitory and have a greater postsynaptic density than type I synapses. Type I synapses are inhibitory and have larger active zones than type II synapses. Type II synapses are excitatory and have flattened synaptic vesicles. p Which of the following is not a classification type of neurotransmitters? small-molecule nucleic-acid gas peptide p Small-molecule neurotransmitters are: synthesized in the soma and packaged in the terminals. synthesized in the terminals and packaged in the soma. synthesized in the soma and packaged in the soma. synthesized in the terminals and packaged in the terminals. p Which of the following is not part of the amine subtype of small-molecule neurotransmitters? dopamine glycine serotonin norepinephrine p Which of the following is not an amino acid neurotransmitter? dopamine glutamate histamine GABA p.166 4
