ASSIGNMENT ABOUT NERVOUS SYSTEM:-

The nervous system is a complex network of nerves and cells in our body. They help in carrying messages from spinal cord to the brain and from the brain to the spinal cord and also to the various parts of the body.

The nervous system is a complex network of nerves and cells in our body. They help in carrying messages from spinal cord to the brain and from the brain to the spinal cord and also to the various parts of the body.The nervous system is of two types the Central nervous system and the Peripheral nervous system. The Central nervous system consists of the main control centers the brain and spinal cord and The Peripheral nervous system is further divided into Somatic and the Autonomic nervous systems.

The nervous system is the reason that we are able to communicate with the outside world. The system also helps in controlling many mechanisms in our body at the same time. These are the few functions which are controlled by the nervous system on daily basis.

• The nervous system helps in taking the information from the outside that is happening to our body.
• The nervous system helps in taking the information from the outside that is happening to our body.Our senses help us to gather that information and then send it to the control panel- the brain.

• The nervous system helps in taking the information from the outside that is happening to our body.Our senses help us to gather that information and then send it to the control panel- the brain.The processing the information is done by the brain.The signal or the message is sent by the brain which helps us in performing the certain action like making our muscles move or feel pain.

For example, if we mistakenly touch a hot plate. Our first reflex is to pull back your hand. A long procedure occurs during this period of seconds. The nerves help in sending the pain signals to the brain, which in turn sends the signal to move the muscles to remove our hand. Therefore, the nervous system is a system that helps us in interacting with our environment. Any derangement in the system can be detrimental to the patient as he or she will not able to feel or react to any stimuli.

$\huge\mathfrak{Answer :}$

$<I>$

$\huge\mathfrak\blue{Nervous\: System :}$

The control and coordination in Animal controlled through the two system

1. nervous system

2. endocrine system .

let us explain about nervous system

=============================

1...Nervous system --The nervous system is a complex network and cells that carry message from brain and spinal cord to all parts of body

➡The function of nervous system is to cordinate the activities of our body

➡it control the system for all our action ,thinking. and behaviour .

➡the nervous system helps all other system of our body to work together ..

☢The unit of Nervous system : Neuron.

Neurons system is made of spinal cells called Neuron

☸Neuron is the largest cell in the body (looks like a electric wire )

the neurons carry message in te form of electrical signals called electrical impulse or nerve impulse .

⚛A Neuron has three main components

1. cell body

2. Dendrites

3. Axon

1. Cell body -- the cell body of a neurone is like a typical animals cell which contains cytoplasm and neucleus .

2. Dendrites --The shortest fibre on the body of a neurons are called dendrites .

✡It carries impulse towards the cell body

3. Axon -- the longest fibre on the. cell body of a Neuron is called axon .it forms fine branches terminal .

It is a long uniformly thikened fibre like process of Neuron .

☮Axon is also known as nerve fibre .

☣now some other part of Neuron ..

Cyton --The cyton or cell body which contain a central neucleus and cytoplasm with characteristics deep stained particle is called neuleons granual .

Synapse --The axon passes the impulse (or message ) to another neurons through a junction called synapse )

~~~~~~~~~~~~~~~~~~~~~~~~~

nurons are of of three types .

1. sensory nurons

2. motor neurons

3. relay neurons

1. sensory neurons transmit impulses from the sensory cell .towards the central nervous system

2. Motor neurons transmit impulses from the central nervous system towards the muscles cells

3 Relay neurons occurs in the central system Nervous system where they serve as links between other neurons .

,we will now explain how nerve impulses are transferred from one Neuron to another un the Nervous system

Any two neurons in the Nervous system don't join to one another completely ,there is a very ,very small gap between two neurons is known as synapse the nerve impulses are carried over this small gap between a pain of neurons by means of a chemical substance called neurotransmitter substance and synapse contact neurons and as we know the receptor in sense organ is in touch with the dendrites of sensory neurones .

~~~~~~~~~~~~~~~~~~~~~~~~~

➡THE ORGAN HUMAN NERVOUS SYSTEM

The main organ of the Nervous system are :Brain ,spinal cord and nerves .

✔How the Nervous system work

_______________________

when the sense organ (like ,eyes ,ears tongue ,nose , or skin )in our body is effected ,it sends the message to brain on the form of electric impulses (called nervous impulses) through the sensory neurones .the brain analyses of the concerned body part and desides the action to be taken the brain send out instructions to the muscles of the concerned to the instruction sent by the brain .

➖>in the process of complicated response (which require thinking ) both , the brain and spinal cord are involved ,but in the simple response (which don't require thinking ).the spinal cord is involved..

⏺THE PART OF NERVOUS SYSTEM ON THE BASIS OF ORGAN.

1.Central nervous system --(consisting of brain and spinal cord .

2. Peripheral nervous system .(consisting of all the Nervous of the body like cranial nervous ,spinal nervous and visceral nerves ) .
