Introduction
In this course, I studied the most important concepts related to the structure and function of the human nervous system. The first significant ideas we were introduced to in the lectures were the theses about the importance of this part of the body. It was revealed that the nervous system is responsible for basic processes, including regulation of all organ activities, cognitive activity, as well as human interaction with the environment. Further, the structure of this structure in the organism was considered in detail. In this part of the course, I encountered a particularly large amount of new information.
Discussion
I had not anticipated that all nerve activity could be divided into two sections, including the central and peripheral. The former includes the spinal cord and brain, which contain a large network of vessels that transport necessary substances. The peripheral system includes all the endings that run from the above organs to the tissues of the entire body. An important insight that has changed my perception of all human nervous activity is the division of the system into somatic and autonomic. All human actions and internal and external reactions can always be attributed to one of these functions. Somatic implies innervation and provision of all processes under control, while autonomic implies excitation and maintenance of metabolic processes.
Conclusion
Any mental changes in a person are due to a shift in the balance toward one of these spheres, hence a healthy state is considered to be a balanced operation. I used to think that the nervous system has one general function and is not subdivided into levels depending on interrelation with the consciousness. The information I studied allowed me to reconsider my ideas about what processes ensure the nervous activity of people.
