Because earthworms are vulnerable to predator assaults and agricultural activities, nature has endowed them with the ability to regenerate destroyed body segments. In the lack of a defined nonneural endocrine gland, the cerebral neurosecretory system is likely to play a key role in wound healing and body segment regeneration. The purpose of this research is to look at the cytomorphological changes in the cerebral neurosecretory cells after amputation in the topsoil Indian earthworm Lampito mauritii. Dissected cerebral ganglia were fixed in Bouin's solution and processed for traditional neurosecretory staining techniques: Paraldehyde Fuchsin (AF) and Chrome Alum Haematoxylin Phloxin after posterior amputation of the earthworm with a paragon knife (CAHP). Following transection of 10 posteriormost body segments, a wave of muscle contraction was observed along the anteroposterior direction of Lampito mauritii's body. Following posterior amputation of body segments, cerebral...
