A Study on the Anatomic and Histological Structures of Magpie (Pica pica) Glandula Uropygialis.

The study aims to investigate anatomical, histological and morphometric structures of the magpie’s (Pica pica) glandula uropygialis living in Turkey. Magpies were anesthetized and common carotid artery was cut for blood draining. Then abdominal organs were removed and fixed in the 10% formaldehyde solution and glandula uropygialis was dissected. Then, glandula uropygialis tissues passed alcohol and xylene series and embedded in paraffin blocks for histological analyses. The blocks were cut and obtained 7 μm thickness of section were stained with Crossman Modified Triple staining. Magpie (Pica pica)’s glandula uropygialis located on 3 and 4. caudal vertebra and pygostyl under the integument and it was observed that consisted of bilateral two lobes as right and left. In histological analyses, there were holocrine glands covered by connective tissues and these glands opened a same duct in the papilla. It was determined that glandula uropygialis is a simple tubular holocrine gland and this gland covered by connective tissues. [ABSTRACT FROM AUTHOR]
