4. In the space below explain the conditions that give rise to the resting membrane potential. What is the role of membrane permeability in regulating membrane potential? Imagine a neuron with no dendrites and 1m axon. The distance between nodes of Ranvier 1mm. Cell body diameter 20m. Axon internal diameter 10m. Assume normal concentration of potassium and sodium: [K+]inside=140mM;[K+]outside=4mM[Na+]inside=15mM;[Na+]outside=150mM
