The Function of the Nervous System of the human body in 2020

 Hello Readers Welcome To The Site ” “

And I Am The Author Of This Site And Today I Tell You About Nervous System Which Is Expanded In All Over Body And Controls All Functions Of The Body.

Introduction:
Human Nervous System Is A Major System Which Controls Upon All Function Of Human Body And The Smallest Unit Of Nervous System Is Neuron Or Nerve Fibre.

TYPES OF NERVOUS SYSTEM:

• CNS (Central Nervous System)
• PNS (Peri-Pheral Nervous System)
• ANS (Actiral Nervous System)

CNS:
CNS Is A Type Of Nervous System Which Contains Its 2 Major Constituent Parts Such As:
1.Brain
2.Spinal Cord

Brain:

Brain Is A Very Sofisticated Part Of Human Body Which Is Present In Cranial Cavity Of Human Body And Responsible For All Functions. All Functions Are Sensed And Interpreted By Brain. Brain Is Responsible For Storage Of Various Memories.

Brain Is Divided Into Its 3 Constituent Parts On The Basis Of Their Function And Area Such As:
1.Forebrain
2.Mid Brain
3.Hind Brain

Fore Brain:

Fore Brain Is The Initial Part Of Brain And Has Divided Into 4 Parts Such As:
1.Cerebrum
2.Thalamus
3.Al Factory Lobes
4.Hypothalamus

Cerebrum:
Cerebrum Covers The 60% Area Of Fore Brain And Responsible For Intelligence Reasoning And All Mind Abilities. Cerebrum Is Present In One Pair In Cerebral Hemisphere

Thalamus:
Thalamus Is Another Part Of Fore Brain Which Is Responsible For Entering Or Releasing The Information Which Is Entered Into Brain.This Is Also Called GateKeeper.

Al Factory Lobes:
This Is A Lobe Structure And Are Responsible For Detect Any Type Of Smell.

HypoThalamus:
Hypo Thalamus Is Responsible For Control The Voluntary Activities Such As Talking, Walking, etc. This Is Also Responsible To Control Some Involuntary Activities Such As Thirstyness, Hunger,etc.

Mid Brain:

Mid Brain Is Responsible For Cordination Between Fore Brain And Hind Brain.
This Is Divided Into 2 Parts Such As:

 
1.Corpora Quardigamina
2.Crura Caribri

Corpora Q.:

 
This Is A Lobe Like Structure And Contains 2 Lobes Such As:
1.Auditory Lobe
2.Optic Lobe

Auditory Lobe:
Auditory Lobe Is Responsible To Detect And Sound Waves.
Optic Lobes:

 
Optic Lobe Is Responsible To Visualize Any Object.
Crura Caribri:

 
Crura Caribri Is Responsible For Co-Ordination Between Mid Brain And Hind Brain. Crura Caribri Is Also Known As the Co-Ordination System.

Hind Brain:
Hind Brain Is The Last Chamber Of Brain And Divided Into 2 Parts Such As:
1.Cerebellum
2.Pons

Cerebellum:

Cerebellum Covers 80% Part Of Hind Brain And Present In Cerebellum Hemisphere. Cerebellum Is Responsible For Some Rapid Fire Activities.

Pons:
Pons Is Responsible To Control Muscle System.

Spinal Cord:
Spinal Is Another Part Of CNS And Made Of Large Number Of Neurons And Responsible For Information Transfer.

PNS:
PNS Is Another Type Of Nervous System Which Mainly Include Neuron.

Neuron:
Neuron Or Nerve Fiber Which Is Smallest Unit Of Nervous System And Responsible For Information Transfer.Neuron Transfer The Information By The Process Of Synopsis.Neuron Mainly Consists Of Some Parts Like Cyton Or Cell Body Which Is The Head Part Of The Neuron And Nerve Ending Which Is End Part.

Types Of Neuron:
Neuron Is Mainly Divided Into 3 Types:
1.Sensory Neuron
2.Motor Neuron
3.Relay Neuron

Sensory Neuron:
This Type Of Neuron Is Responsible To Intake The Impulse From Effected Organ And Take It To CNS.

Motor Neuron:
Motor Neuron Is Responsible For Intake The Impulse From CNS And Transfer To Effected Organ

Relay Neuron:
Relay Neuron Is Responsible For Co-Ordination Between Sensory And Motor Neuron.

ANS:
ANS Only Contains Medulla Oblengata Which Controls The Involuntary Activities Of Human Body And It Has Different Centers Like Circulatory Center, Digestive Center And Respiratory Center.

Note:
Synepsis: This Is A Process In Which Impulse Is Transferred From One Neuron To Another Neuron. This Process Is Occured Between The Cytons Of 2 Neurons. This Process Is Done By The Help Of Neuro Transmitter Which Is An Acetyle Colin.
