I don’t get why is possible to regrow a lot of stuff (skin, muscles, broken bones etc.), but only to a certain extend. At one moment you are suddenly not able to rebuild things.

Why is that and what determines what we can regrow?

    The cell is programmed to be self-regulating. Because if its not you call that cancer, and the cell would either commit suicide or get killed by immune cells. I think that selective pressures determine what cells needs a higher turnover rate. Because skin is more important to replicate than neurons.
