Central nervous system


The autonomic nervous system is considered a functional component of the human body while in contrast the central nervous system and the peripheral nervous system are considered structural components of the human body. The central nervous system plays a key and vital role in body orientation, coordination of bodily movements, assimilation of experience, and playing out the behaviors driven by instinct.

The brain, as intensely intelligent, detailed, and complexities along with the myriad of generous pathways of electrical communications complete the central nervous system.


The endocrine system joins with the central nervous system in order to organize and effectively manage the functions of other body systems. The brain is a much more significant system unto itself, with its complete abilities beyond the scope of current comprehension. The brain is responsible for everything from personality, thoughts, functions, autonomous function, dysfunctions, to the command center for the body and its systems. While even Plato recognized the brain’s complexities and its vast wonders, referring to it as the “divinest part of us,” the brain has yet to be comprehended even on an immature level.

Neurology as it is applied as the study of brain function, has often been coined the final frontier of human anatomy. Nobody really expects to ever fully understand the brain and all its vast capabilities, but neurologists make a huge effort in understanding its potential. The next several decades are expected to reveal more information about the brain, but with the unveiling of new information of this sort, there always seems to be an accompanying list of questions.

The nervous system is organized into three basic functional and structural categories, the central nervous system, the autonomic nervous system, and the peripheral nervous system. The autonomic nervous system is the key to involuntary functions such as breathing and maintaining a heart rate. The peripheral nervous system is primarily responsible for centralized communication. The central nervous system is the primary nervous system with the largest communications network within the human body. While the autonomic nervous system shares some responsibilities with the central nervous system, all three segmented nervous system categories are always working in constant continuity with each other.


The central nervous system is ingeniously designed to respond to stimuli both internally and externally. The nervous system, through the use of neurons, make human beings aware of their environment as well as their own bodily needs. When a person feel pain when they touch the hot stove, the nervous system is responsible for alerting the body not only of the pain but also of the movement required to remove the hand from the hot stove.

Nerve cells, which are highly sensitive to conductibility as well as excitability, are the main communicators within the central nervous system. Nerve cells transmit information to the brain and often transmit the required response. The endocrine system assists the central nervous system in body coordination and activities that require multiple systems to function simultaneously (which is nearly all activities) but the central nervous system also has the capabilities to “remember” experiences and coordinate the body’s responses appropriately.


The four basic function of the central nervous system (orientation, coordination, assimilation, and programming) requires constant and vigilant monitoring of the body’s internal and external stimulus as well as a remembered and controlled response to the stimulus. Integration, which is the process of interpreting the changes in stimulus, usually produces a response requirement from the muscles or glands.

The central nervous system has a finely tuned, highly developed capacity for interpretation of stimulus as well as the ability to sense, integrate, and control the motor response necessary. This ability allows the human body to function and remain remarkably safe while maintaining homeostasis of the body. Without the central nervous system, the human body would not survive. Either it would forget to tell the heart to beat or the sense of pain would remain undetected and danger would lead to death..
