What are the different healing rates of epithelial tissue and nervous tissue?

Epithelial tissue generally has a high healing rate due to its ability to rapidly regenerate and replace damaged cells, aided by its rich blood supply and stem cells. In contrast, nervous tissue has a limited healing capacity; when injured, it often leads to permanent damage because mature neurons do not readily regenerate. While peripheral nerves can show some regeneration, central nervous system injuries typically result in lasting deficits due to scar formation and inhibitory environments.
