GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -This process of reorganization, called morphallaxis, is the most efficient way for simple organisms to regenerate. Higher animals, with more complex bodies, regenerate parts differently, usually by the production of a specialized bud, or blastema, at the site of amputation.

Detailed explanation-3: -Salamanders, planarians and a number of other species regrow damaged or missing body parts. This is regeneration. Some human organs, e.g. liver and skin, also regenerate when they are damaged.

Detailed explanation-4: -Some tissues such as skin, the vas deferens, and large organs including the liver can regrow quite readily, while others have been thought to have little or no capacity for regeneration following an injury. Numerous tissues and organs have been induced to regenerate. Bladders have been 3D-printed in the lab since 1999.

Detailed explanation-5: -Regeneration is one of the processes in which if an organism is cut into several pieces, each of its parts regrows to the original state. This process is carried out by specialized cells called stem cells. It takes place in organisms that have a very simple structure with very few specialized cells.
