Question
The following are changes in the nervous system of the aged except:Question 20Select one:a.The autonomic nervous system performs effectivelyb.Loss of nerve cells contribute to a progressive loss of brain massc.There is reduction in the synthesis and metabolism of the major neurotransmittersd.Reduction in cerebral flow.
Solution
To answer the question, we need to identify the option that does not describe a change in the nervous system of the aged. Let's analyze each option:
a. The autonomic nervous system performs effectively: This option suggests that the autonomic nervous system functions properly in the aged. This is a change in the nervous system of the aged, so it is not the correct answer.
b. Loss of nerve cells contribute to a progressive loss of brain mass: This option states that the loss of nerve cells leads to a progressive reduction in brain mass. This is a change in the nervous system of the aged, so it is not the correct answer.
c. There is a reduction in the synthesis and metabolism of the major neurotransmitters: This option indicates that there is a decrease in the production and breakdown of the major neurotransmitters. This is a change in the nervous system of the aged, so it is not the correct answer.
d. Reduction in cerebral flow: This option suggests that there is a decrease in blood flow to the brain. This is a change in the nervous system of the aged, so it is not the correct answer.
Based on the analysis, the correct answer is option a. The autonomic nervous system performs effectively.
