Preksha Dhyana ;
There are two main divisions of this system-(i) The parasympathetic and (ii) sympathatic. The action of the two divisions is antagonistic. In general, the parasympathetic system exerts its influence during the time of rest ; the sympathetic system prepares the body for emergency conditions and aids in the mobilization of body resources and energy production. Functional Organization
More than 10 billion neurons comprise the human nervous system. Through the intricate network run impulses that are the foundations of creative thoughts as well as desires. Innumerable bits of data continually flood the body's sensory-organs and pass from the receptors along the peripheral system to the central nervous system. The latter system screens and evaluates the incoming impulses ; stores important data for future retrieval; formulates decisions and initiates actions via impulses sent along the peripheral nerves to the muscular system.
Thus the nervous system has two basic functions-(i) the detection and processing of information from within and outside the body and (ii) production and regulation of movement by muscle-section. Some parts of the brain are also responsible for the control of emotions and the storage of information and are also concerned with personality and intellect.
We shall now examine the components of each division of the nervous system in greater detail.
1. The Central Nervous System A. BRAIN
The brain is the most complex and the most important part of the nervous system. In it are the sites of consciousness, thought, memory, creativity, speech, vision, hearing, smell, control of endocrine glandular secretions and autonomic (involuntary) functions, and the will to carry out purposeful actions. It is only because of the brain (his or hers and our own) that we know anything of the personality of an individual. Inspite of incredibly immense progress made by the electronics technology, a living human brain is a far more compact, yet complex and efficient apparatus
