(0.5 pt) Neuroglia Description Astrocytes Controls environment around neuron cell bodies in the PNS Ependymal cells Controls environment around neurons in the CNS Microglia Produces myelin in the PNS Oligodendrocytes Produces myelin in the CNS Satellite cells Lines CSF-filled cavities in the CNS Schwann cells Destroys debris and foreign material in the CNS 8. What type(s) of signal(s) does an afferent neuron carry? (0.25 pt) a. only sensory signals going to the CNS b. only sensory signals going away from the CNS c. only motor signals going to the CNS d. only motor signals going away from the CNS e. both sensory signals and motor signals f. either sensory signals or motor signals depending on the exact neuron 9. What type(s) of signal(s) is/are carried by a nerve that is connected to your spinal cord at one end and your toe at the other end? (0.25 pts) a. only sensory signals going to the CNS b. only sensory signals going away from the CNS c. only motor signals going to the CNS d. only motor signals going away from the CNS e. both sensory signals and motor signals f. either sensory signals or motor signals depending on the exact nerve Questions 10-11 refer to the diagram below which shows a simplified view of the circulation of fluids in the adult brain. 10.
