Hi everyone.
It is interesting, are there anywhere discribed full (complete) and consistent structure of human's nervous system in tree-like manner. For example, NS consists of central and peripheral NS, the CNS consists of Cerebrum and Spinal cord, and so on till separate nuclea and nervous paths.
Dear Sir, please refer this book ------ Anatomy of the human body : "Gray, Henry, 1825-1861 "comprised and gifted by Henry Grays who is mentioned as Father of Human Anatomy to all Mankind. Thanks
Everything you're looking for, and more, can be found on the website "Brain Atlas/Brain Map" and stand-alone application "Brain Explorer" from the Allen Institute of Brain Science.
It is meant to show which genes are expressed in each brain region, but when you query the system it presents a nested list of structures that is exactly what you're looking for.

Nervous System: Facts, Function & Diseases

Neurons in the brain communicate via electrical impulses and neurotransmitters.

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring.
Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system. According to the National Institutes of Health, the central nervous system is made up of the brain, spinal cord and nerves. The peripheral nervous system consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect to one another and to the central nervous system.
Functionally, the nervous system has two main subdivisions: the somatic, or voluntary, component; and the autonomic, or involuntary, component. The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing, that work without conscious effort, according to Merck Manuals. The somatic system consists of nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin.
Description of the nervous system
Nerves are cylindrical bundles of fibers that start at the brain and central cord and branch out to every other part of the body, according to the University of Michigan Medical School.
Neurons send signals to other cells through thin fibers called axons, which cause chemicals known as neurotransmitters to be released at junctions called synapses, the NIH noted. A synapse gives a command to the cell and the entire communication process typically takes only a fraction of a millisecond.
Sensory neurons react to physical stimuli such as light, sound and touch and send feedback to the central nervous system about the body’s surrounding environment, according to the American Psychological Association. Motor neurons, located in the central nervous system or in peripheral ganglia, transmit signals to activate the muscles or glands.
Glial cells, derived from the Greek word for "glue," are specialized cells that support, protect or nourish nerve cells, according to the National Institute on Aging. [Related: 10 Things You Didn't Know About the Brain.For more plz read at folowing link

Dear Alberto, thank you. I perfectly know that site, but it give anatomic division in mixed manner (gray and white matter), rather than functional division. I'm looking for consistent functional division. Something like cybernetics scheme of human's NS.
Dear, Nirmala. Thank you very much for links, but there is no answer on my question there. i'm looking for consistent and complete functional scheme.
