The reason for the flow of a small number of sodium ions through the Na+ channel needs to be explained. Concept introduction: Diffusion is defined as the movement of particles such as atoms, molecules or ions from a higher concentration region to a lower concentration region. This process is continued till the concentration of the particles is same on both sides of the membranes or boundary. In the body, the diffusion of ions/molecules/atoms takes place inside or outside of the cell through the cell membrane.
