The process of regeneration is somewhat intricate and involves multiple organization highlighting replacement of the lost parts through reawakening of morphogenesis at the late phase of ontogeny. The characteristics of this process may be epimorphic or morphollactic has been stated by several developmental biologists. Indeed the exact definition of the regeneration is difficult to ascribe and several investigators have attempted to define the phenomenon on the basis of their observations be it on recapitulation of development processes (progressively restricted by age) reconstitution of the lost parts physiological parameters cellular and sub cellular level or phyllogenetic status of the organism concerned and so on. In short it may be stated as anatomical growth established on the later stages of ontogenesis to re establish the physiological process in the long run.
The present investigation embodies the following perspectives:
Cephalic regenerative potentials in M.peguana .
- Week wise growth and development of the regeneration blastema.
- Sequential development of the nerve ring .
- Correlated cytomorphic changes in the ganglionic neurosecretory elements.
- Relationship of the neurosecretory elements and their moniliform axon terminals and fibers with extra and intraganglionic vascularization and the exposition of the neurosecretory granules at the accumulation sites--- A Lightmicroscopic observations
