An action potential (AP) is the mode through which a neuron transports electrical signals. It is defined as a brief change in the voltage across the membrane due to the flow of certain ions into and out of the neuron. In this article we will discuss how an action potential is generated and how conduction of an action potential occurs.What is the action potential of a neuron?
Only neurons and muscle cells are capable of generating an action potential; that property is called the excitability. This article will discuss the definition, steps and phases of the action potential.What are the events that take place during an action potential?
There are three main events that take place during an action potential: 1 A triggering event occurs that depolarizes the cell body. 2 Depolarization - makes the cell less polar... 3 Repolarization - brings the cell back to resting potential. 4 Hyperpolarization - makes the cell more negative than its typical resting membrane potential.What is the difference between membrane potential and action potential?
During the resting state, the membrane potential arises because the membrane is predominantly permeable to K+. An action potential begins at the axon hillock as a result of depolarisation.
