Potencial de Membrana (transmembrana o reposo) facil

Every cell in the body has a membrane potential, which is the difference in charge between the internal environment and the cell. The membrane potential is -90 mV when the cell is at rest, but when a stimulus is present, this cell is altered and its membrane potential changes to an action potential. What is the membrane potential? When the cell is at rest, cells have a membrane potential because the cell is in an electrochemical equilibrium of the electrolytes present in the intracellular and extracellular environments. The objective of this video is to explain the basic theory of why the cell is electronegative at -90 mV. I hope you like the video, and if so, please leave me a like and comment.
