Chapter 41.3, Problem 1C
Summary Introduction
To describe: The role of ion channels and sodium pumps neuron in achieving resting potential.
Introduction: A neuron is the basic functional unit of the nervous system. It forms the complex network of specialized cells of the nervous system for the transmission of synapse. It is a microscopic individual cell that has the ability to respond to a stimulus and convert it into an action potential.
