An axon is the relativelylong tail-like part of a neuron, or nerve cell. Theoutersurface of theaxon membrane (dielectric constant = 5, thickness = 1 x10-8 m) ischarged positively, and the inner portion is charged negatively.Thus, the membrane is a kind of capacitor. Assuming that an axoncan be treated like a parallel plate capacitor with a plate area of4.90x10-6 m2, what is its capacitance?
