Question 8

The major parts of the nervous system are the PNS and CNS.

The major parts of the nervous system are the Peripheral Nervous System (PNS) and the Central Nervous System (CNS). These components work together to control and coordinate bodily functions.

A) PNS and Somatic Nervous System

This option is incorrect because while the PNS is a major part of the nervous system, the Somatic Nervous System is not a separate entity but rather a subdivision of the PNS. Therefore, this option does not accurately represent the primary components of the nervous system.

B) Autonomic Nervous System and CNS

This choice is partially correct in that the CNS is a major part of the nervous system. However, the Autonomic Nervous System is also a subdivision of the PNS, not a standalone major component. Thus, this option fails to represent the two distinct major parts as required.

C) PNS and CNS

This option is correct as it identifies the two major parts of the nervous system: the Peripheral Nervous System (PNS) and the Central Nervous System (CNS). The PNS connects the CNS to limbs and organs, while the CNS processes information and coordinates activity, making this pair essential to understanding the nervous system's structure.

D) Autonomic Nervous System and Somatic Nervous System

This option is incorrect because both the Autonomic and Somatic Nervous Systems are subdivisions of the PNS. Therefore, listing them as major parts of the nervous system does not accurately reflect the primary components.

Conclusion

The correct answer is C, as it clearly identifies the PNS and CNS as the major components of the nervous system. All other options either include subdivisions or incorrect pairings, failing to represent the essential structure of the nervous system accurately. Understanding these components is crucial for comprehending how the nervous system functions as a whole.
