Summary Introduction

To determine:

Myelinated nerve fiber responsible for the conduction of action potentials.

Introduction:

The nerve fiber or an axon is an extended portion of cell body, which conducts action potential to transmit information to the effector organs. There are myelinated and unmyelinated axons, based on the presence or absence of myelin sheath around it, respectively. The conduction of action potential through the unmyelinated axon is not effective as charges leak out of the axon membrane. While, the myelinated axon helps to conduct action potential because of thick myelin sheath which protects the charge leakage.
