Summary Introduction

To determine: The effect of high extracellular concentration of Na⁺ on neurons.

Introduction: Nerves relay messages from the sensory organs to the central nervous system. Additionally, they carry the messages from the central nervous system to muscles and other organs. The messages are carried by the nerves in the form of electrical impulses. The signals that reach the cell body stimulate the neuron to generate its own signal in the form of an action potential, and relay it to the next neuron or the effector organs.
