Question

write a detailed note on nervous tissue. No spamming ​

Answer 1

ANSWER

• It consists of neurons or nerve cells.

• It is responsible for control and communication among the body parts.

It consists of two types :-

• Neurons - Transmits electrical impulses

• Neuroglia - Supports and protects neurons.

The nervous system is also divided majorly into 2 types :-

The central nervous system - Includes the brain and spinal cord.

The peripheral nervous system - Consists of all the body nerves.

write a detailed note on nervous tissue

Plants and animals have different tissues. In animals, there are four types of tissues namely:

• Connective Tissue
• Epithelial Tissue
• Muscular tissue
• Nervous Tissue

What is a Nervous Tissue?

Nervous or the nerve tissue is the main

tissue of our nervous system. It

monitors and regulates the functions

of the body. Nervous tissue consists of

two cells: nerve cells or neurons and

glial cells, which helps transmit nerve

impulses and also provides nutrients

to neurons. Brain, Spinal Cord, and

nerves are composed of nervous

tissue, they are specialized for being

stimulated to transmit stimulus from

one to another part of the body rapidly.

Structure Of Nervous Tissue

It is made 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 called the Target cells, thereby passing impulses

The main part is the cell body which contains the nucleus, cytoplasm and cell organelles. Extensions of the cell membrane are referred to as processes.

Dendrite is a highly branched processes, responsible for receiving information from other neurons and synapses (specialized point of contact). Information of other neurons is provided by dendrites to connect with its cell body.

Information in a neuron is unidirectional as it passes through neurons from dendrites, across the cell body down the axon.

Nervous Tissue Location

The nerve tissue or the nervous tissue is the chief tissue component of the two major parts of the nervous tissue – Central nervous system(CNS) formed by the spinal cord and the brain and the branching peripheral nerves of the peripheral nervous system (PNS) that control and regulate the functions of the body and their activities.

The nervous tissue is located in the

peripheral nerves all through the body

and also in the organs of the central

nervous system such as the spinal

cord and the brain. The nervous tissue

consists of the nerve cells or the

neurons. Neurons are specialized cells

that react to stimuli by generating

signals through the axons, which are

elongated structures arising from the

cell body.
