The brain is the main organ of a person that controls all his life functions, determines his personality, behavior and consciousness. Its structure is extremely complex and is a combination of billions of neurons grouped into departments, each of which performs its own function. Many years of research have made it possible to learn a lot about this organ.
What parts does the brain consist of?
The human brain is made up of several sections. Each of them performs its function, ensuring the vital activity of the body.
According to the structure, the brain is divided into 5 main sections.
Among them:
- Oblong. This part is a continuation of the spinal cord. It consists of nuclei of gray matter and paths from white. It is this part that determines the connection between the brain and the body.
- Average. It consists of 4 tubercles, two of which are responsible for vision and two for hearing.
- Rear. The hindbrain includes the pons and cerebellum. This is a small department in the back of the head, which weighs within 140 grams. Consists of two hemispheres fastened together.
- Intermediate. Consists of thalamus, hypothalamus.
- Finite. This section forms both hemispheres of the brain, connected by the corpus callosum. The surface is full of convolutions and furrows covered by the cerebral cortex. The hemispheres are divided into lobes: frontal, parietal, temporal and occipital.
The last section occupies more than 80% of the total mass of the organ. Also, the brain can be divided into 3 parts: the cerebellum, the trunk and the cerebral hemispheres.
In this case, the entire brain has a coating in the form of a shell, divided into three components:
- Cobweb (cerebrospinal fluid circulates through it)
- Soft (adjacent to the brain and full of blood vessels)
- Hard (contacts the skull and protects the brain from damage)
All components of the brain are important in the regulation of life and have a specific function. But the activity regulation centers are located in the cerebral cortex.
The human brain consists of many departments, each of which has a complex structure and performs a specific role. The largest of them is the final one, which consists of the cerebral hemispheres. All this is covered with three shells that provide protective and nourishing functions.

What functions does it perform?
The brain and its cortex perform a number of important functions.
Brain
It is difficult to list all the functions of the brain, because it is an extremely complex organ. This includes all aspects of the life of the human body. However, it is possible to single out the main functions performed by the brain.
The functions of the brain include all the feelings of a person. These are sight, hearing, taste, smell and touch. All of them are performed in the cerebral cortex. It is also responsible for many other aspects of life, including motor function.
In addition, diseases can occur against the background of external infections. The same meningitis that occurs due to infections of pneumococcus, meningococcus and the like. The development of the disease is characterized by pain in the head, fever, pain in the eyes and many other symptoms such as weakness, nausea and drowsiness.
Many diseases that develop in the brain and its cortex have not yet been studied. Therefore, their treatment is hampered by a lack of information. So it is recommended to consult a doctor at the first non-standard symptoms, which will prevent the disease by diagnosing it at an early stage.
