Have you ever wondered how a neuron responds to different stimuli?, or because it has the ability to generate electrical responses? Or even, what is it that causes a neuron to generate such quick responses? These and other questions are of great importance to understand not only the neurons, but also the muscle cells, two of the excitable cells of the body.
In different videos we will deal with the analysis of the electrical properties of the membrane, we will briefly review how the membrane and its components behave as an electrical circuit, we will learn how the resting membrane potential is generated and finally we will conclude by reviewing the action potential, one of the most important electrical signals that occur in two of the excitable cells, neurons and muscle cells.
At the moment we will concentrate only on the neuron, although the electrical process can be equivalent in all cells and especially the potential generation of action is very similar in the neuron, in the skeletal and smooth muscle, while in the cardiac muscle it is a little different for the characteristics of its ion channels, we have in mind that we are describing the electrical phenomenon, not the mechanical one, which is exclusive of the muscle cells and that we will approach later in another video dedicated to this.
Finally something of great importance for the cell that you can also learn about Don Gibbs balance and the Nernst equation
