Nervous Tissue || Animal Tissues (Part 5) || in Hindi for Class 9

In this Science (Biology) video in Hindi we explained the structure and functions of nervous tisssue for class 9th. This is a topic of Chapter 6 of science from NCERT.

Animal tissues can broadly be categorized into four types, viz., epithelial tissue, connective tissue, muscular tissue and nervous tissue.

𝑵𝒆𝒓𝒗𝒐𝒖𝒔 𝑻𝒊𝒔𝒔𝒖𝒆 − It coordinates and controls many body activities by stimulating muscle contraction. It creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.

Nervous tissue is the 𝑚𝑎𝑖𝑛 𝑡𝑖𝑠𝑠𝑢𝑒 component of the 𝑛𝑒𝑟𝑣𝑜𝑢𝑠 𝑠𝑦𝑠𝑡𝑒𝑚.

Nervous system is categorized mainly into two types, viz., central nervous system and peripheral nervous system. Central nervous system includes the brain and the spinal chord. Peripheral nervous system connects different body parts with the central nervous system.

Nervous tissue is composed of 𝑛𝑒𝑢𝑟𝑜𝑛𝑠 and 𝑔𝑙𝑖𝑎𝑙 𝑐𝑒𝑙𝑙𝑠.

𝑵𝒆𝒖𝒓𝒐𝒏 -
It communicates with other cells using nerve impulse.
It is the main functional unit of the nervous tissue.
Main parts of neuron are cell body, dendrites, axon, nerve endings.

𝑮𝒍𝒊𝒂𝒍 𝒄𝒆𝒍𝒍 -
They provide support and protection for neurons.
Glial cells include oligodendrocytes, astrocytes, ependymal cells, microglia, Schwann cells and satellite cells.
These cells have four main functions:
(1) to surround neurons and hold them in place
(2) to supply nutrients and oxygen to neurons
(3) to insulate one neuron from another
(4) to destroy pathogens and remove dead neurons.
