Establishing membrane potential
WebResting membrane potential describes the steady state of the cell, which is a dynamic process that is balanced by ion leakage and ion pumping. Without any outside influence, … The membrane potential in a cell derives ultimately from two factors: electrical force and diffusion. Electrical force arises from the mutual attraction between particles with opposite electrical charges (positive and negative) and the mutual repulsion between particles with the same type of charge (both positive or both negative). Diffusion arises from the statistical tendency of particles to redistrib…

So there's lots of different ions that have high concentrations outside the neuron compared to lower concentrations inside the neuron, or vice versa.
WebResting Membrane Potential Image by BYUI JH, 2013 Above is a diagram of a cell establishing a resting membrane potential. Shown are representations of a K+ channel that allows for the movement of K+ out of the cell, a closed Na+ channel that prevents movement of Na+ into the cell, and a Na+/K+ ATPase pump that moves three Na+ ions … WebQuestion: The sodium-potassium pump is involved in establishing the resting membrane potential True False The inflow of sodium ions into the intracellular fluid (ICF) causes depolarization of the neuron's inner cell membrane.
