INTRODUCTION:-

GENERATION AND CONDUCTION OF NERVE IMPULSE:
NEURONES ARE EXCITABLE cells because their membrane are in a polarised state.Different types of ion channels are present on the neural membrane.These ion channels are selectively permeable to different ions.

When a neuron is not conducting any impulse resting the axonal membrane is comparatively more permeable to potassium ions and nearly impermeable to sodium ions.

The human neural system is divided into two parts the central neural system and the periphere neural system.

The centre neuro system includes the brain and a spinal cord and he is the site of information processing and control.
Peripheral neural system comprises of all the nerve of the body associated with the central nervous system brain and spinal cord.
Peripheral neuro system of two types:-
Efferent fibers and afferent fibres.

The afferent nerve fibres transmit impulses from tissue organ to the central nervous system and the efferent fibres transmits regulatory impulses from the central neural system to the concerned peripheral tissues or organs.

The periphere neurosystem is divided into two divisions called somatic neural system and autonomic neural system.
The somatic neural system release in pulses from the central neural system to skeletal muscles while the autonomic neural system transmits impulses from the central neural system to the involuntary organs and smooth muscles of the body.

Autonomic neural system is
further classified into sympathetic neural system and para sympathetic neural system.

A neuron is a microscopic structure composed of three major parts namely cell body, dendrites and axon.
The cell body contains cytoplasm with typical cell organelles and certain granular bodies called Nissl’s granules.
