Microstructure of the pituitary gland and ovary in postnatal ontogenesis of Daghestan newborn rock sheep

The pituitary gland consists of the anterior, intermediate, tubular lobe, which is defined as the adenohypophysis, and the posterior lobe - the neurohypophysis. The anterior part of the pituitary gland is built of epithelium, between the rows of which there are thin interlayers of the connective tissue. By the nature of the perception of histochemical dyes, adenocytes are subdivided into chromophobic and chromophilic. Chromophobes are classified as slightly differentiated cells, in the cytoplasm of which there is no granulation. Acidophilic adenocytes, round-shaped cells, scattered throughout the gland's surface, often found in the form of clusters, are isolated from the chromophilic structures. Histochemical data indicate that lipids and ascorbic acid, which are necessary for hormonopoiesis, are revealed in gonadotropocytes and theca cells.
