Write a Short Note on Nervous Tissue

Nervous tissue

• Nervous tissue is the main tissue of our nervous system and is located in the peripheral nerves all through the body.
• It consists of two cells Neurons and supporting cells called Neuroglia, or Glial Cells.
• Brain, Spinal Cord, and nerves are composed of Nervous Tissue.

4 Types of Nervous tissue

There are four types of nerves on the basis of functionality:-

1. Sensory
2. Motor
3. Autonomic
4. Cranial

Structure of Nervous Tissue:

• Made up of nerve cells or neurons, all of which consists of an axon. 
• Axons are long stem-like projections emerging out of the cell, responsible for communicating with other cells.
• Dendrite is a highly branched process and is responsible for receiving information from other neurons and synapses.
• Information of other neurons is provided by dendrites to connect with its cell body.

Function of Nervous Tissue:

• Generates and carries out nerve impulses. 
• Produce electrical signals that are transmitted across distances.
• Responds to stimuli.
• Carries out communication and integration.
• Provides electrical insulations to nerve cells and removes debris.
• Carries messages from other neurons to the cell body.
