A large motor neuron runs from the brain to the arm. The neuron contains a core of bundled microtubules. If the motor neuron is 40 cm long, and the magnitude of the potential difference from the top of the neuron to the bottom is 40 mV, then what is a reasonable estimate for the magnitude of the cross sectional area of the neuron? Take the resistivity of the microtubule to be about 40 MO/um.
