The document discusses the complexity and functionality of the human brain, highlighting its role as the central organ controlling bodily processes through sensory input and decision-making. It explains the structure of the brain, including various parts such as the cerebrum, cerebellum, and brain stem, as well as the nervous and endocrine systems. Additionally, it describes the function and communication of neurons, emphasizing the importance of neurotransmitters in transmitting information between nerve cells.

2. Introduction
The most complex, mysterious, and important part of the human body is the
brain. Although everything in human existence is governed by the brain, the
human concept of the brain is still in its infancy. Despite the invention of
technology such as the supercomputer to conquer space, the knowledge of the
brain inside the skull is still very vague. The gap between the knowledge of the
brain, that is, self-knowledge, and man is an ocean.

3. Controller of all processes
The brain keeps people connected to their surroundings. By combining and
processing the information transmitted by the five senses, the brain enables
people to make decisions based on new information. This is to save the person
from harm or danger and to ensure that everything in the body works properly.
And to do this, the brain is constantly monitoring everything that is happening
inside the body, what is happening outside the body, what is happening in the
environment. The brain is at the heart of all communication in the body. He has
all the information inside the body.

4. Wonderful organ
The weight of the brain is about one and a half kg. It consists of two types of cells. Neurons and glial cells.
The ratio of glial cells to neuron cells is 1:10. That is, there are 10 glial cells opposite a neuron cell. And the
number of these neuron cells is about 100 billion. One neuron connects to another neuron through fine fibers
dendrites and axons.

5. Cerebral
The cerebral lobes of the brain are evenly divided into two parts divided by the
middle of the nut. One part is called the right ring and the other part is called the left
ring.
But since these two have a horizontal connection, the right ring controls the left side
of the body and the left ring controls the right part of the body.
The left ring between the two rings remains active in most people. The left ring
controls speech, myths, numbers, logic, language, appetite, digestion, and thoughts.

6. Cerebrum
The largest part of the brain is the cerebrum. It occupies most of the skull. The cerebrum is divided into two
parts. Right and left. These two rings are connected by a bunch of white nerves. The inner part of the
cerebrum is made up of white matter.

7. Cerebellum
This part of the brain is called the cerebellum. It is located below the occipital
lobe of the cerebrum. Like the cerebrum, the cerebellum is composed of white
matter in a circle of gray matter.
Inside the white matter is again the gray matter area. This is called the
cerebellum nucleus. There are two rings here. These two rings are connected by
vermis. Controls and adjusts the speed of the cerebellum muscles. This results in
coordination between each posture. You can easily do things like wiping a cold
handkerchief by pressing your nose.

8. Brain stem
The brain stem connects the higher centers of the brain with the spinal cord. Its main organs are the medulla
oblongata, pons, midbrain, thalamus, and hypothalamus.

9. The medulla oblongata
Inside the medullary white matter is gray matter. The four cranial nerve centers that control all conscious
activity of the head, neck, and shoulders are located here. There are more important control centers inside the
medulla.

10. Midbrain
The midbrain connects with the upper cerebrum and the lower cerebellum and
pons. It also looks like medulla and pans.
There is also a cluster of nerves, which descends from the brain to the lower
spinal cord and ascends to the upper cerebral cortex.

11. Thalamus
A little above the thalamus midbrain is a gray substance covered by white matter. It is a major relay center.
Every massage from the lower area of ​​the brain and the spinal cord is processed here and sent to the
cerebral cortex.

12. Hypothalamus
The hypothalamus is located below the thalamus. The hypothalamus is a very important organ in the brain.
This, in conjunction with the pituitary, ensures the continuity of the surviving biochemical environment located
inside the body.
The hypothalamus ensures that normal body temperature is maintained. This is because the hypothalamus is
extremely sensitive to any temperature fluctuations. It controls food intake because it is sensitive to the pain
and persecution of hunger.

13. Sensory organ
One of the major functions of the brain is to take the necessary action by analyzing the information obtained
through the five senses of the human being. You feel it only when the senses inform you about any external
change. What the senses are making you feel is change.
If you become accustomed to a particular feeling, such as the weight of the clothes on your body or the
location of the hat on your head. Then you never consciously feel it. Then your feelings adapt to it. But if there
is any change in this condition, the body has to take the necessary steps to maintain the balance of the
biochemical system of the body.

14. Communication between the brain and the body
All the senses of the body are connected to the brain or spinal cord by nerve fibers. When a sense receives
information, it produces electrical waves in the nerve fibers. These waves travel to the destination through the
nerve fibers. Sometimes it takes action automatically or through voluntary action and sometimes the brain
consciously takes action by feeling it.

15. Nervous system
The internal communication system, known as the nervous system, is a combination of multiple
communication systems.
1. The central nervous system is made up of the brain and spinal cord.
2. The peripheral nervous system is made up of the central nervous system and the nerves that communicate
with the organs and muscles of the body.
3. The autonomic nervous system is a part of the peripheral nervous system. The autonomic nervous system
monitors and controls the functions of internal organs without your conscious effort. It is again divided into two
parts.

16. Endocrine system
Being able to respond quickly in any situation is a feature of the nervous system. The endocrine system, on
the other hand, works slowly and on time. The endocrine glands produce hormones and release them into the
blood and transmit them throughout the body through the blood.

17. Neurons
The brain and nervous system are made up of billions of tiny neurons. Neurons are the strongest unit in the
brain. Its size and shape depend on its position and responsibilities.
However, every neuron has a nucleus and a cell body surrounded by it. And from this neuron cell,
innumerable nerve fibers known as axons and dendrites have gone around like wires.

18. Transmitting information
Nerve fibers communicate with the brain, with muscles, with glands, and with each other. But they do not
touch each other. The action of a neuron, the fiber that transmits information from a neuron, is called an
action, and the dendrites of other neurons, which receive information, are called dendrites. This is called the
synapse. When electrical charges are formed in a nerve, the process of transmitting information from one
neuron to another or a muscle begins.

19. Neurotransmitter
We learn about the brain’s neurotransmitters through a story. The story of the Incas. Reaching Machu Picchu,
the fortified city of the Incas, was a daunting task. The first step was to cross the 17,000-foot-high mountain
range of Mount Andes.
Anyone who lamented the lack of oxygen would be able to reach the city gate by crossing the 3,000 steps
made of stone, even after seeing the city above the clouds.
