What would happen if a neuron lost its myelin sheath? A. Na + would leak out of the axon leaving too few ions to stimulate the Na channels at the next node to open. B. The neuron would die. C. More Na + channels would be exposed allowing freer entry so conduction speed would increase. D. More K + channels would be exposed allowing freer exit so the cell would hyperpolarise.
Option A. If a neuron lost its myelin sheath then Na + would leak out of the axon leaving too few ions to stimulate the Na channels at the next node to open.
