Myna
Definition:
(n.) Any one of numerous species of Asiatic starlings of the genera Acridotheres, Sturnopastor, Sturnia, Gracula, and allied genera. In habits they resemble the European starlings, and like them are often caged and taught to talk. See Hill myna, under Hill, and Mino bird.
Example Sentences:
(1) When orchidectomized, the adrenals of semi-domestic, adult common myna, Acridotheres tritis atrophied.

(3) The low dose of reserpine in the passerine (common myna and bulbul) birds resulted in 40-84% reduction of both norepinephrine (NE) and epinephrine (E) from the adrenal glands irrespective of its nerve supply.
(4) The primordial oocytes in the myna ovary are loosely arranged in groups or nests, whereas in crow they form compact nests surrounded by highly vascularized connective tissue bands or lie in layers beneath the surface epithelium.
