Use the relationship between resistance, resistivity, length, and cross-sectional area to estimate values of resistance of a membrane segment Rmem and an axoplasm segment, Raxon, using the following order-of-magnitude values. (Hint: Think about the geometry of the azon and the membrane) :
the diameter of the axon ~10 µm
the membrane thickness ~10 nm
the resistivity of the axoplasm ~1 2-m
the average resistivity of the membrane ~ 108 2-m the segment length ~1 mm
