Epimorphosis is the term used to describe the regenerative process by which an organism regrows a lost or damaged tissue or organ. There are several synonyms for the word "epimorphosis," including regeneration, regrowth, restitution, recovery, and rejuvenation. These terms all describe the same basic process of the body repairing or replacing damaged or missing tissue. While epimorphosis is most commonly associated with the regeneration of limbs and other body parts in certain animals, such as salamanders and starfish, it is a fundamental process that occurs throughout the natural world, including in human tissues like skin and liver.
