Question

The cranial nerves are the part of

• A. Somatic nervous system
• B. Peripheral nervous system
• C. Central nervous system
• D. Cardiovascular system

Hint:

Brain/Cord = Central. Everything else (Cranial/Spinal nerves) = Peripheral.

Answer 1

The Correct Option is B

Step 1: Concept
The nervous system is divided into structural and functional components.

Step 2: Meaning
The Central Nervous System (CNS) consists of the brain and spinal cord. The Peripheral Nervous System (PNS) consists of all nervous tissue outside the CNS.

Step 3: Analysis
Cranial nerves originate from the brain but extend out to the body. Because they are outside the primary "central" axis of the brain/cord tissue itself, they are categorized as part of the PNS.

Step 4: Conclusion
Thus, cranial nerves along with spinal nerves make up the peripheral nervous system.

Final Answer: (B)
