This chapter discusses axonal physiology. Topics covered include the energetic aspects of conduction, ionic basis of the nerve impulse, conduction velocity in axons, inhomogeneity of channel distribution in mammalian myelinated nerve, and complementary distribution of sodium and potassium channels in the mammalian node and internode.
Keywords: myelinated axons, nonmyelinated axons, conduction, nerve impulse
