 - Cytoplasmic Conductivity: The concentration of ions and other conductive materials in the cytoplasm affects axial resistance. A higher concentration of conductive ions leads to low axial resistance.
 - Diameter of the Neuron: Larger diameter axons have lower axial resistance because a greater cross-sectional area allows for easier ion flow. This is why larger axons can conduct signals more rapidly.
