Abstract
1. The neurosecretory system of Varanus griseus consists of the nucleus supraopticus, nucleus paraventricularis, an infundibular pathway, neurosecretory fibers in the median eminence and pars nervosa. 2. The nucleus paraventricularis is larger in size than the nucleus supraopticus and its cells are strikingly large with big nuclei and nucleoli. 3. The pars nervosa forms the largest part of the pituitary body and is highly lobulated. 4. Nissl substance in the neurosecretory cells was found to occur among peripheral massive form of neurosecretory granules and in the powdery form. 5. It was pointed out that starvation accelerates the rate of release of vasopressin-adiuretin as was shown by the change in the histological structure of the nucleus supraopticus and the nucleus paraventricularis and in the amount of the stainable Gomori material in the pars nervosa. 6. Severe starvation caused degeneration of neurosecretory cells of nucleus supraopticus and nucleus paraventricularis and depletion of Gomori material in pars nervosa.
