Diagnosis and treatment of heart diseases due to changes in the coronary vascularization need a detailed knowledge on the morphology and possible variations of the aortic valves and coronary ostia. This study was performed to clarify details on morphology of these structures in domestic cats. The tricuspid aortic valve was examined in 65 domestic shorthair(More)
BACKGROUND The European bison (Bison bonasus) is an endangered species. More information on its anatomy is needed as only few studies have been published. This study is the first report on the morphology of the coronary vessels. Given the anatomical similarity between the European bison and other ruminants, the results of this study can be applied to other(More)
The aim of this study was to elaborate criteria defining the morphotype and to perform a morphological and morphometric analysis of the squamous part of the occipital bone and of the foramen magnum in the European cat. The study material comprised 50 corpses of European cats of both sexes and of bodyweight from 1.35 to 7.7 kg, aged from 1 year to 17 years.(More)
The Harderian gland (HG) in birds is the dominant orbital gland, which plays an important role in immunological response. Tissue sections taken from adult females of Bilgorajska goose were stained with hematoxylin-eosin, Azan, PAS, AB pH 2.5, AF and HDI. Based on the histological structure the HG in Bilgorajska geese had compound tubular structure with(More)
Normal structure of the accessory organs of the eye is essential for normal eye physiology. Among the most important accessory organs of the eye are the eyelids, the conjunctiva-associated lymphoid tissue (CALT) and the lacrimal gland (LG). The aim of this study was to demonstrate the histological structure of the eyelids and LG by histochemical and(More)
BACKGROUND The anatomy of the adrenal glands has been widely studied in many species of domestic and wild mammals. However, there are no available literature reports describing the morphology and morphometry of the adrenal glands of the European bison (Bison bonasus). RESULTS The study was conducted on 97 European bison of both sexes. The growth of the(More)
The present investigation was performed on 50 ostriches from 28th day of incubation until the 7th month of life. The morphological (morphometric, histological, histometric and histochemical) studies were conducted. Tissue sections were stained with haematoxylin-eosin, methyl green-pyronin Y, periodic acid-Schiff, alcian blue pH 2.5, aldehyde fuchsin and(More)
BACKGROUND Recent new anatomical and histological features of craniocervical junction in dogs and cats were described providing evidence of differences between the carnivore species. No information on these structures in foxes exists. RESULTS Two parts of the alar ligaments were found. A longer one aroused from dens of axis to the internal (medial)(More)
