Question

The cranial and spinal nerves are included under
A) Autonomic nervous system
B) Peripheral nervous system
C) Central nervous system
D) Cutaneous nervous system

Answer 1

Hint:Cranial nerves originate from the brain and pass information between the brain and the different parts of the body. Spinal nerves originate from the spinal cord and the body.

Complete answer:
To answer this question, we must know about the types of nervous system.
The nervous system is the main control machinery of our body. It controls everything we do like breathing, walking, thinking, feeling.. It also comprises the nerves which carries messages to and from the different body parts.
The nervous system comprises of two parts:
>The central nervous system- The central nervous system comprises the brain and spinal cord. The brain controls almost all bodily functions. Spinal cord is the pathway through which messages are sent to and from the brain.
>The peripheral nervous system- the peripheral nervous system comprises the nerves which originate from the brain (cranial nerves) and spinal cord (spinal nerves). The primary role of the peripheral nervous system is to connect the brain and spinal cord to the organs, hands and legs, skin.
Autonomic nervous system-It consists of nerves which controls the organ. The sympathetic and parasympathetic nerves carry messages.
Cutaneous nervous system- It comprises autonomic nerves and sensory nerve fibres.

Thus the correct answer is option (B).

Note:A spinal nerve carries motor, sensory and autonomic signals. There are 31 pairs of spinal nerves which are present on either side of the vertebral column. There are 12 spinal nerves which are spread in the head and neck.
