Why is the mode of conduction of electrical impulse along the myelinated neuron advantageous to a non mmyelinated neuron ? What is this type of conduction called ?

What is myelin ? How are myelinated neurons differnet from unmyelinated neurons ?

The outer covering of non- myelinated neurons in brain is

Electrical impulse travels in a neuron from

The non-myelinated neurons can be located in

Distinguish between the following pairs : Conduction of nerve impulse in myelinated and non myelinated nerve fibres

Nerve impulses are conducted more rapidly in myelinated fibres than in non-myelinated fibres.

Why does distilled water not conduct electricity, whereas rain water does?

What is action potential? Describe how the nerve impulse is propagated in a non-myelinated and myelinated nerve fibre.

A : Presence of myein sheath increases the rate of conduction of nerve impulse. R : Ionic channels are absent in the area covered by myelin sheath therefore, depolarization occurs only at the nodes of Ranvier , resulting in saltatory or jumping conduction.

Why does an aqueous solution of an acid conduct electricity?
