Multiple Choice: Circle the answer that best completes the statement. (2 points each) Which of the following statements regarding cells in the human nervous system is CORRECT? a. There are more interneurons than glia. b. Sensory neurons outnumber interneurons. c. Most neurons are multipolar. d. There are more glial cells in the peripheral than central nervous system.

Each of the following is a function of astrocytes EXCEPT: a. myelination of axons in the central nervous system b. regulation of cerebral blood flow by buffering potassium ions c. providing structure and support to the nervous system d. guiding neuronal migration during development

The cytoskeletal protein that transports HRP anterogradely is: a. neurofilament b. neurotubule c. microfilament d. microtubule

Each of the following terms in the pair are closely related to each other EXCEPT: a. in situ hybridization and protein b. PET scan and radioisotope c. transneuronal transport and virus d. synapse and electron microscope

Each of the following statements regarding the spinal cord are correct EXCEPT: a. The cauda equina begins around the first and second lumbar vertebrae and extends through the sacral and coccygeal vertebrae. b. During development, the faster growth of the vertebrae relative to the spinal cord causes a shift in the relative position of the spinal cord within the vertebral column. c. The cauda equina is composed of the spinal nerves of the lumbar, sacral, and coccygeal spinal segments. d.
