Question

question 9 of 10
this consists of the brain and the spinal cord:

a. central nervous system.

b. parietal nervous system.

c. reticular activating system.

d. limbic nervous system.

Explanation:

In the field of Biology (a subfield of Natural Science), the central nervous system is defined as the part of the nervous system that consists of the brain and the spinal cord. The parietal nervous system is not a standard term for this structure, the reticular activating system is a part of the brain involved in arousal, and the limbic nervous system (more commonly limbic system) is related to emotions and memory, not the combination of brain and spinal cord. So the correct answer is A.

Answer:

A. central nervous system.
