...However, the response of adrenal medulla to osmotic stress is highly variable; in the pigeon, adrenaline is the hormone mobilized during osmotic stress whereas in the house sparrow, both noradrenaline and adrenaline are secreted (Ghosh et al., 2001)....

...Moreover, the domestic pigeon (Columba livia) did not show “exocytotic figures” in the adrenomedullary chromaffin cells after treatment with lithium chloride (Ghosh et al., 2001)....

...PNMT exists in its active form only in the adrenaline-storing cells (Ghosh et al., 2001)....
[...]
...Insulin, in birds as in mammals, causes depletion of noradrenaline from the adrenal glands and increases adrenaline synthesis; glucagon induces the release of catecholamines (Ghosh et al., 2001)....
[...]
...In addition, the structural and functional integrity of the avian adrenal gland depends on the vagus nerve, because vagotomy causes a hypertrophy of cortical tissue and an atrophy of chromaffin cells (Ghosh et al., 2001)....

...Clusters of chromaffin cells are mixed with blood vessels and the interrenal steroidogenic cells are radially arranged in the subcapsular zone and in the inner part of the gland (reviewed by Ghosh et al., 2001)....

...PNMT exists in its active form only in the adrenaline-storing cells (Ghosh et al., 2001)....
[...]
...The avian adrenal chromaffin tissue is influenced by the steroidogenic cells; GCs increase noradrenalin content in the chick and adrenaline content in the pigeon adrenal glands, with a synergistic action requiring activity of the splanchnic nerve (Ghosh et al., 2001)....

...Different biogenic amines and neuropeptides localized in medullary cells may regulate corticosterone secretion from interrenal cells via a paracrine mode of communication (cf. Nussdorfer 1996)....
