As we all know, the brain is the part of the human nervous system, located centrally which controls almost all the activities of the human body. The human brain is considered one of the largest and most complex organs in the human body as the human brain is composed of 100 billion nerve cells. The human brain also has many specialised areas which help in the communication process and both these nerve cells and specialised areas work together. The major part of the central nervous system is the brain which is located in the head and is covered by a protective covering known as the skull.
Parts of the Brain
Further, the brain is divided into three parts, they are:
A. Cerebrum:
It is considered the largest part of the brain, which covers mostly your skull area. The cerebrum is further divided into right and left hemispheres. The main function of the cerebrum is interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement. 85% percent of the human brain consists of the cerebrum.
B. Cerebellum:
The cerebellum is also termed as little brain as it is small in size and located under the cerebrum. Its main function is in controlling coordination, muscle movements, maintaining posture, muscular activity and balance.
C. Brain Stem:
It is situated below the cerebrum and also in the front of the cerebellum, and is made up of medulla oblongata, pons and midbrain. It works as a connecting part for the cerebrum and cerebellum to the spinal cord. Its major function is to control the flow of messages with the body, performing many automatic functions such as breathing, digestion, sneezing, swallowing, pumping of the heart, body temperature, sleeping, coughing, vomiting, etc.
Brain Diseases
It is a kind of infection that occurs in the brain, because of various harmful factors. Based on infection, brain disease is of various types. Some of the major brain diseases are inflammation, trauma, tumours, stroke, seizures, etc. And all these disease tumours are considered to be life-threatening.
About Tumour
When there is an abnormal growth of tissue inside the brain, it is termed as the brain tumour. A brain tumour is further categorised into two types: malignant (cancerous) or benign (non-cancerous) and this tumour can happen at any age.
Classification of Brain Tumour
A. Primary brain Tumour:
This type of tumour generally begins from the brain is termed as the primary brain tumours. They are considered to be very dangerous and they can either be malignant or benign tumours.
B. Secondary Brain Tumour:
This kind of tumours are formed in some other part of the body rather than the brain and further they spread into the brain.
