AORTA HISTOARCHITECTURE OF GALLIFORMES AND ANSERIFORMES
Abstract
The paper studies peculiarities of aorta histological structure of galliformes (hen and guinea fowl) and anseriformes (Italian goose and Pecking duck). The research shows aortic wall of the birds has developed tunica intima and tunica media; the outer coat consists of connective tissue fine fibers. Architecture of collagen fibers and their density in the aortic wall are characterized by the fact that fine collagen fibers coloured locate in narrow cellular layer in the external elastic membrane. The dense high-curved fibers shape cellular-layer view in internal elastic membrane. The space between internal elastic membrane and external elastic membrane is characterized by the thickest collagen fibers reviewed in layers which consist of long and straight or slightly-curved fibers and loose layers which consist of collagen fibers of different density, thin curve fibers and zigzag fibers. The smooth-muscle cells reviewed as 14–15 thin circular layers when smooth-muscle tissue moves from one layer to another make the third part of medial. The research shows dense coloured long fibers and zigzag elastic fibers are expressed in the goose and duck. The fibers slightly coloured can be straight or slightly curved. The paper reveals goose’s 16 layers of collagen fibers are alternated by elastic fibers.
