 - Ion Channels: The presence and density of ion channels directly affect membrane resistance. More channels result in lower resistance because they provide additional pathways for ions to flow.
 - Membrane Composition: The lipid bilayer structure and the types of proteins embedded in the membrane influence its overall resistance. A thicker membrane will have higher resistance.
