Question

18. A virus has attacked neurons of the somatic sensory system of your patient. This virus 'hides out' or lives in the cell bodies of 2nd order neurons. You have developed a drug to inactivate or 'kill' the virus but it must be applied near to where the virus is located. Where would you deliver this drug? In the... a. thalamus b. primary motor cortex c. postcentral gyrus d. dorsal root ganglia e. dorsal gray horn 19. Much information is contained in the name of a tract found in the white matter of the spinal cord. Which of the following is / are true regarding the posterior spinocerebellar tract? MARK ALL THAT APPLY a. it ends in the cortex of the cerebrum b. it begins in the spinal cord c. it carries motor information d. it carries sensory information e. it begins in the cortex of the cerebrum 20. The upper motor neurons of pyramidal or direct pathway tracts that you consciously control are located in the: a. thalamus b. dorsal gray horn c. postcentral gyrus d. primary motor cortex e. dorsal root ganglia 21. The pineal gland releases this hormone at night. It is involved in regulating the sleep/wake cycle. a. melanin b. dopamine c. melatonin d. serotonin e. gonadotropin-releasing hormone [GnRH] 22. If we were to connect you to an EEG machine and measure your brain waves while taking this exam, you would likely exhibit waves that are irregular, high frequency, and have a relatively low amplitude compared to deep sleep waves. These would be considered. a. alpha b. beta c. theta d. delta e. all these would be measured. 23. A patient arrives in the ER appearing to be under the influence of drugs. Despite shining a light into his eyes, his pupils are still dilated or enlarged. The drug he has taken stimulates: a. cannot determine-need more information b. afferent signals to the primary sensory cortex. c. efferent signals from the primary motor cortex. d. parasympathetic system e. sympathetic system 24. Some children are born with a disorder in which they cannot sense pain. Which receptors are affected? a. mechanoreceptors b. chemoreceptors c. proprioceptors d. thermoreceptors e. nociceptors
