Question

The spinal cord is a part of ........... nervous system.

• A. Autonomic
• B. Somatic
• C. Peripheral
• D. Central

Hint:

Remember that the nervous system has two "central" components that form the main axis: the brain and the spinal cord. Everything else that branches off is "peripheral."

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The question asks to identify the major division of the nervous system to which the spinal cord belongs.
Step 2: Detailed Explanation:
The nervous system is broadly divided into two main parts:
1. The Central Nervous System (CNS): This is the main control center and consists of the brain and the spinal cord.
2. The Peripheral Nervous System (PNS): This consists of all the nerves that branch out from the CNS (brain and spinal cord) and extend to other parts of the body, such as muscles and organs.
The Autonomic and Somatic nervous systems are further subdivisions of the Peripheral Nervous System (PNS).

Autonomic Nervous System: Controls involuntary functions like heartbeat and digestion.
Somatic Nervous System: Controls voluntary muscle movements.
Since the spinal cord, along with the brain, makes up the primary processing center of the nervous system, it is part of the Central Nervous System.
Step 3: Final Answer:
The spinal cord is a part of the Central nervous system.
