1 Neuroscience I—Exam 1 October 2, 2008 Please blacken in (DO NOT CIRCLE) the one best answer to each question on the answer sheet. You can keep the questions but be sure to hand in the answer sheet. 1. All of the following statements about neurons and glia are correct EXCEPT: a) there are more glial cells than neurons in the human brain b) there are more glial cells than synapses in the human brain c) the largest neurons in the brain are larger than the largest glia d) there are about 1 trillion glia in the human brain e) there are over 100 different cell types in the human brain 2. Which of the following cell types provide myelin insulation for neurons in the central nervous system? a) Astrocyte b) Chandelier cell c) Oligodendroglial cell d) Schwann cell e) Stellate cell 3. All of the following diseases primarily involve glial cells EXCEPT: a) astrocytoma b) glioma c) oligodendroglioma d) multiple sclerosis e) rabies 4. Which of the following statements about axons and dendrites is correct? a) Dendrites are more likely than axons to have spines b) There are usually fewer dendrites on a neuron than axons c) Dendrites generally have uniform diameter along their length whereas axons taper d) Dendrites can extend several meters in some animals e) The axon membrane is similar to the soma membrane; the dendrite membrane is quite different from the soma membrane. 5. In the process of protein synthesis within neurons: a) It occurs more in axons than the soma b) DNA leaves the nucleus through pores so that transcription can take place in the cytosol c) Gene expression is the reading of DNA to make protein d) Proteins are delivered to the synapse via retrograde axoplasmic transport e) Tiny workers toil night and day for minimum wage

All the following statements about axoplasmic transport are correct EXCEPT: a) It is responsible for the loss of myelin in multiple sclerosis b) It requires ATP c) In herpes simplex, retrograde transport delivers the virus to the soma where it replicates d) Slow transport could take over a year to cover the length of a long axon e) Kinesin is involved in anterograde transport 8. All of the following statements about the differences between the endocrine and nervous system are correct EXCEPT: a) The nervous system takes less time to transmit messages from one location to another. b) When an endocrine cell releases a chemical messenger nearly every cell in the body is exposed to this message. c)
