Summary Introduction

To explain: The way by which nerve impulse is conducted in unmyelinated neurons and in myelinated neurons.

Introduction: Neurons are brain cells that are specialized to transmit nerve impulses. In vertebrates, neurons play an important role in the flow of information. In myelinated neurons, axons of the neuron are wrapped around with thin myelin sheath (produced by Schwann cell) on the outer surface. It provides insulation to cells and speeds up the electrical signal conduction.
