Within the nervous system, the (a) are to the ganglia as a tract is to a (b).
To understand the analogy between the nervous system components, we need to first clarify what each term represents:
(a) Ganglia: Ganglia are small clusters or groups of nerve cell bodies located outside the central nervous system (CNS). They function as relay stations, processing and transmitting information between different parts of the body.
(b) Tract: In the nervous system, a tract refers to a bundle or group of nerve fibers (axons) that are located within the central nervous system. These tracts serve as pathways for transmitting signals between different regions of the brain, spinal cord, and other parts of the body.
Now, let's address the analogy:
The analogy is comparing (a) ganglia to (b) tracts. To find the answer to the analogy, we can analyze the relationship between the given terms.
Ganglia are to the nervous system as tracts are to the central nervous system.
From this relationship, we can infer that ganglia and tracts are both components of the nervous system, with ganglia being specifically located outside the central nervous system (CNS), and tracts being located within the CNS.
Therefore, the correct answers are:
(a) Ganglia are to the nervous system as a tract is to the (b) central nervous system (CNS).
