Up to present moment, comparative morphology of the preddure-cochlear organ in poultry has been studied insufficiently, as required by biology and veterinary medicine. This was the basis for the proposed research. This is a separate section of complex scientific-research work of the department of morphology, physiology and pathology of the Orenburg state agrarian University. A sufficient amount of experimental material, which was achieved by the use of anatomical, histological and morphometric methods, identified the regularities of the specific features of morphology preddure-cochlear organ of hens, ducks and geese. Findings complement the accumulated information on the morphology and physiology of the preddure-cochlear organ of birds and are intended to form the basis of comparative morphological and functional studies that will confirm the number of well-known general biological laws and clarify these questions for a particular species. These materials have a certain theoretical and practical significance and can be used when writing the relevant sections of comparative anatomical guidelines, training and manuals on the species, age and breed anatomy of birds, in teaching in the veterinary, zoo- and biological faculties. They are also can supplement the studies in research institutes and laboratories studying sensory systems in general and preddurecochlear body in particular. The results may be considered by clinicians in the study of pathogenesis, the development of methods for the treatment and prevention of diseases of the outer, middle and inner ear, in the design and conducting of surgical procedures.
