What is the Function of the Human Nervous System
Control is the power of restrain & regulation by which a process can be started, showed down or stopped.
Coordination is orderly working of different but inter related parts to perform one or more activities very smoothly.
There are 2 modes of control & coordination, chemical & nervous. Plant do not have a nervous system. They possess only chemical controls & coordination.
Animals have both chemical & nervous control & coordination.
Human Nervous System
It is the system of nervous organs, nerves & neurons that form a network throughout the body for conducting information via electrical impulses so as to coordinate & control activities of different parts as well as provide appropriate response to both internal & external stimuli.
Structure of nerve cell :
Neuron or nerve cell is a structural and functional unit of nervous system that is specialised to receive, conduct and transmit impulses. It is very long, sometimes reaching 90-100 cm. A neuron has three parts— cell body, dendrites and axon. The term neurites is used for both dendrites and axon.
