Explain the structure and function of a neuron.

Neuron has a central part called the cell body or cyton. Many thread-like branches extend from the cyton. These thread-like branches extending from all sides of the cell body are called dendrons. Dendrons further divide to form dendrites. One of these extensions is longer than the rest and is called the axon. Functions of neuron:

1. Neuron help in the control and coordination of the body.
2. The information or message is transmitted by a neuron in the form of impulses and in one direction only.
3. Many neurons or nerve fibres bound together constitute a nerve.
