title: Comparative cytomorphology of the avian adrenocortical tissue.
abstract: The histology and histochemistry of the interrenal gland of twenty avian species have been described in this report. The avian interrenal tissue, on the basis of nuclear orientation and other cytomorphic features, can be classified into six cytologically distinct types. Cytomorphic organization within the interrenal tissue of these avian species also indicates some regional demarcation into subcapsular and central zones. Zonal demarcation in the interrenal tissue of these birds has also been indicated from chemocytological investigation. Paradoxically not much of correspondence was noticed in the cytologic and cytochemical patterns. The cytological and cytochemical studies fail to indicate any phylogenetic trend within the interrenal tissue of the birds under investigation.
