morphallaxis - regenerationthis kind of regeneration takes place in plants sponges and coelenterates such as jelly fishes and hydra the missing parts
epimorphic regenerationin this sort of regeneration the lost part is reformed and restored via the growth of a bud or blastema from the remaining
reparative regeneration this type of regeneration as the name suggests involves repair of a wound or replacement of a body part removed intentionally
regeneration - development biologyregeneration has intrigued scientists for several generations and has resulting in voluminous literature on the
physiological regeneration this type of regeneration is a regular physiological function including the continuous replacements of cells and tissues
comparison between metamorphosis in amphibians and insects you may have realized that the metamorphic process in amphibians and insects show certain
interaction of insect hormones in the process of metamorphosis the organs and the hormones usually included in metamorphosis of insects this is since
prothoracic gland or ptc prothoracic gland ptc or moulting gland and ecdysone or moulting hormonethe 3rd endocrine gland-prothoracic gland- is an
brain neurosecretory cells and their hormones kopec was the very first to suggest the role of hormones in controlling metamorphosis on the base of
external factors - factors controlling metamorphosis in insectsin few cases an external factor may be accountable for initiating moulting as for

general process of post-hatching growth in insects while a young insect hatches out from an egg it is covered by a firm inflexible sclerotized
induction in metamorphosis some of the morphogenetic changes throughout metamorphosis are found fo be quite independent of hormone action for
threshold value of different larval tissues threshold value of dissimilar larval tissues for the thyroid hormone concentrationone of the main
competence of larval tissue or multiple responses the responsiveness of different larval tissues to thyroxine is markedly different the tissues of
hormones in metamorphosis of amphibia in amphibians the changes that take place during metamorphosis are brought about by hormonal secretions of the
morphological changesregressive changes-these changes include the gradual reduction and ultimate disappearance of all those larval structures or
metamorphosis in amphibians metamorphosis is radical in anurans slight or not exists in urodeles in anuran amphibians like toads and most frogs
types of metamorphic changes the process of metamorphosis includes reactivation of the morphogenetic processes the morphogenetic changes also the
types of development of animalsdifferent animals have evolved various methods of development these methods can be broadly categorized into two
