Question

What are the two types of nerves? Write their functions.

Answer 1

Nerves are a collection of neurons, which is a cable-like structure within the body to conduct nerve impulse which relays information from one part of the body to others.

Complete answer:
Nerves are part of the nervous system and are involved in the control and coordination of all the parts of the body. These nerves are made up of a bundle of fibers which are wrapped around layers of tissue and fat and are stretched out throughout the body. These nerves transmit information along the axons to respective organs. The nervous system not only sends and receives the message but they also process them into chemical signals known as an impulse in the human body. A wide network of nerves is spread throughout the body which runs through the brain, the spinal cord, and many organs.
In the human body, nerves are classified based on their functions and these are sensory nerves and motor nerves.
-Sensory nerves; Sensory nerves are the nerves that send signals to the brain or the spinal cord from the sense organs. These nerves are enclosed in the form of a bundle-like structure or nerve fibers in the peripheral nervous system (PNS), and they carry signals from the CNS (central nervous system) to the PNS.
Function- Sensory nerves carry information from the receptor to the central nervous system from where the information gets processed. These nerves are responsible for sensations.
-Motor nerves: Motor nerves are those nerves which carry the signals in the form of a response from the brain or the spinal cord to other parts of the body such as muscles and glands. These nerves are responsible for carrying the information from CNS to PNS.
Function- These motor nerves carry information from the central nervous system to the muscles or glands. They are responsible for controlling the actions and movement.

Note: Depending upon the functions the nerves perform in the human body they are classified as sensory and motor nerves. Nerves make up the peripheral nervous system (PNS) of the body which helps in control and coordination.
