What is the function of the central nervous system?
The main function of the central nervous system is to sort all the information it receives. The system then gives information to control the effect of the human body. Together with the peripheral nervous system located in various organs in the body, the central nervous system acts as a "main control officer" for all physical functions. Its two main parts, the brain and spinal cord, have their own duties that contribute to the general task of the system. It consists mainly of gray and white matter. Gray matter is a place where all information processes take place and contain nerve cell bodies and branched parts called dendrites. On the other hand, white matter acts as a messenger and connects all areas of gray matter to create the correct information process.
In addition to its gray and white matter, the brain is further divided into three parts. The cerebrum is the largest part of the brain and is responsible for all actions that the body consciously does, such as walking or eating. It also provides us with suitable feelings when we use our five sensory organs. Medulla Obrongata located at the back has the task of controlling heart rhythm, breathing and blood flow. For this reason, it can properly carry out a "karate chop" at the base of the neck actually lead to the death of a person.
The third part of the brain is the brain whose task is to oversee the correct coordination and posture. That is why, when you walk, his leg and hand alternately swing back and forth to keep the body in a balanced position. Many theories have emerged that athletes and musicians have more developed brains, because their profession requires to devote themselves to exceptional eye coordination.
The brain may be the "processing center" of the central nervous system, but without spinal cord the brain would not process any information at all. The spinal cord is a channel where all information from the peripheral nervous system travels. In crises, the brain can also send information through the spinal cord to the body organs to adapt to the injury. Like the brain, the spinal cord is also made of gray and white matter. The central nervous system isEssentially formed by nerve cells that are in charge of everything that occurs in the body.
