INTRODUCTION OF BRAIN
Brain lies in the cranial activity and it is covered and protected with a system having three membranes called as meanings. Brain is the most active part of the human body and it works 24/7 without any disturbance. Brain of man is having a complicated structure and has a same parts as other vertebrates. The brain has three divisions name as forebrain or prosen cephalon , midbrain or mesencephalon and hindbrain or rhombencephalon.
The outer brain is been composed of gray matter and the inner brain is composed of white matter. Question arises what is gray matter and what is white matter is the color of brain ?
No it is not the Color of brain but the gray matter is made up of cell bodies of neurons and the white matter is white in color due to presence of fatty myelin sheaths that surrounds the axons.
Do you know there are 7 different main parts in our human brain which are frontal lobe, parietal lobe, Temporal lobe, Pons, Occipital lobe, Cerebelluni, and Medulla oblongata.
HIND BRAIN
Hind brain is the lowest part of the brain and it is the posterior division of the brain. There are 3 main part of Hind Brain Pons varolli, medulla oblongata, cerebellum. This 3 parts are interconnected with each other as shown in the picture.
1)Cerebellum:-
It is the part of the brain which is at back of the skull in vertebrates and lies beneath the optical lobes of the celebrum.
The cerebellum consists of three type of lobes a median lobe and two lateral lobes. The surface of the cerebellum is traversed by numerous furrows or sulci. The words are complicated by i cannot take each and every single word and can explain i am trying to explain as simple as i can do.
2)Pons varolli
This can be also said as Pons also. Its is the bridge if nerve which matter among the various segments of the brain it connects the cerebrum, cerebellum, behind and below the medulla.
It contains bundles of nerves fibres that run very smooth and transversely. It locates above the medulla and below the crura cerebri and in between the lobes of the cerebellum.
3)Medulla oblongata
Medulla oblongata is the lower most part of the human brain and it consists of the two symmetrical halves. Medulla oblongata is also know as spinal bulb. Medulla contains vital nerve centres which controls the main system know as respiration and cardiovascular system.
BRAIN DEATH
Brain death means the whole system of the brain stops working and it might get affected with some disease or some hard injury in brain. It can affect the automatic functions like heart can also be lower due to brain death. Death to patient might occur if there is no Life-support machine and such persons are certified as brain death.
The image shows that the line in between stops that indicate that the brain is stop using and heart is also stop so this causes the patient to death if there are no Life-support machine
COMA
Coma is one of the major problem now a days in brain system it causes due to unconsciousness of brain when it stops the person might go to coma or death.
Coma is also a type of brain disorder. It does not respond or have a connection between the sound, light, or any type of touch. Here the person can only respond to some type of movements such as eye stimuli or even cough and even murmur with lips.
Another type of coma is called deep coma which the persons totally stops the movement gestures nothing he will be blank and he cannot respond to any kind of stimulation. Damage of brain is the main cause of the patient or the person to get in coma.
The person in Coma can come out in a day , week, month, sometimes it take an year to come out the person from coma.If we have kidney problem then also the person can be in comma or taking drugs can be also major reason for the person to go in coma
