Changes in the neurosecretory cells in the brain and thoracic ganglion of UCA (Celuca) Lactea annulipes due to 5-hydroxytryptamine, Octopamine and Dopamine

Study made on the survey of neurosecretory cells between the control and the experimental groups (5-HT, OCT and DOP administered) exhibits the presence of A, B and C type of cells in the brain and A, B, C, and D type of cells in the thoracic ganglia. Among these cells. only 5-HT, OCT, DOP and saline treated groups. Further the staining reaction of the neurosecretory cells of 5-HT treated crabs are comparatively intense than the other treated groups in view of more neurosecretory granules found in the respective neurosecretory cells.
