When you fall down you get hurt or a scratch, your skin is scraped off but after few days it forms again and heels itself. Does the cells in the brain or nervous system get replaced again? (Whoever keeps the answers first and the best I will mark them brainliest and no spam or else I will report)

Answer:
our skin gets repaired because of the formation of clotting by platelets and then the skin cells rapidly divide to recover the area completely, but since our nervous system is very complex, it does not repair itself and thus its damage could cause paralysis and numbness of the area. similarly, the brain cells are also never repaired again
