What is the description of regeneration?

Regeneration is the natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts to full function in plants and animals. Scientists are studying regeneration for its potential uses in medicine, such as treating a variety of injuries and diseases.

What is it called when an animal regrows a limb?

Humans can’t, but some creatures can re-grow their limbs or tails or even their brains! Sometimes, animals even cast off a part of their body on purpose because they feel threatened, and they can re-grow it later — this is called autotomy.

How does regeneration work in animals?

Planarian regeneration involves changes in pre-existing tissues and formation of an outgrowth at wounds called a blastema, in which missing tissues are produced.
