Regeneration by the transformation of existing body tissues.
- ‘Recently we have begun investigations of synaptic molecules up-regulated specifically during morphallaxis.’
- ‘He coined the terms morphallaxis and epimorphosis to describe the two major types of regeneration.’
- ‘The result of morphallaxis is usually a smaller but complete individual, derived entirely from the tissues of part of the original animal.’
- ‘If the body of an intact Hydra is severed in two, it regenerates by morphallaxis, which does not require new growth.’
Late 19th century: from Greek morphē form + allaxis exchange.
