WebStage-3: The neurotransmitter causes sodium ion channels to open, hence the neural membrane becomes polarized, and the impulse carried through the neural cell membrane becomes depolarized. If the potassium ions channel opens, the neural cell membrane becomes hyperpolarized and leads to inhibition of nerve impulse. WebCell polarity refers to spatial differences in shape, structure, and function within a cell.Almost all cell types exhibit some form of polarity, which enables them to carry out specialized functions.
