Abstract

Histological structures and morphometric and some histochemical indicators of elk’s adrenal gland development as subspecies of red deer in prenatal and postnatal ontogenies stages was studied. It was found that the growth of the fetus adrenal glands weight and the thickness of the structures adrenal glands fragments continue throughout the prenatal period of ontogeny. The cells of androgenic zone with single wandering sympathogoniae are differentiated in the adrenal glands in the second month of development. The androgenic and definite zone and the adrenal medulla are differentiated by the third month of development. At the 4 months, adrenal gland cortex zona glomerulosa and zona fasciculate-reticularis are differentiated; zona reticularis is differentiated only by the seventh month. By the eighth month, the structure of adrenal glands corre-sponds to the adrenal glands of a newborn. Full structural formation of the adrenal glands takes place in young ani-mals by age 1.5. Obvious structural changes were not found late in the postnatal stages of development.
