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 bodyâs electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.Of all the diseases of the nervous system, the most common difficulty that people have is pain, and much of that is nerve-related,â according to Dr. Shai Gozani, founder and CEO of NeuroMetrix, a medical device company.
The size of the nervous system ranges from a few hundred cells in the simplest worms, to around 100 billion cells in humans. The central nervous system functions to send signals from one cell to others, or from one part of the body to others and to receive feedback. Malfunction of the nervous system can occur as a result of genetic defects, physical damage due to trauma or toxicity, infection or simply of ageing.
