An average nerve axon is about 4x10-6m in radius, and the axoplasm that composes the interior of the axon has a resistivity of about 2.3 ω ⋅m.
what is the resistance of just 2-cm length of this axon?
provide your answer in mega-ohms (1 mega-ohm = 106 ohms or "millions of ohms").
(note, this value is so large -- it corresponds to the resistance of tens of thousands of miles of the thinnest copper wire normally -- that it explains why a nerve pulse traveling down an axon cannot simply be a current traveling along the axon. the voltage required to achieve a perceptible current in the axon would have to be gigantic! we will investigate how voltage pulses -- not current -- travel down axons in a future lab.)
