    I am a bit confused. Are biological cells and electromagnetic fields good conductors/inducers of electrical impulses?

    Think of the heart and its electrical properties.

    I haven't studied about the heart's electrical properties yet.

    However, are you saying that they both produce electrical impulses?

    sorry, but i don't need info on the heart but i'll read up on it to prepare for my lessons.

    I was talking about cells in general, and if they have any similarities to electromagnetic fields?

    Well for the SAN yes, as the heart is myogenic.

    The heart is triggered by the depolarisation of teh plasma membrane of the cells making up the muscle. And myocardial cells are connected to each otehr by gap junctions, which allow action potential to spread from one cell to another. Thus the initial excitation of one cell eventually spreads and results int eh excitation of all cells.

    It starts in the SAN, where the membrane permeability changes. and through complex system of different equilibrium potential of Na and K etc the membrane is depolarised at a plateau of about 0 mV.

    So yes.
