Some anatomical and histological studies on the arterial supply of the nasal cavity of the buffalo in Egypt (Bos bubalis L.).
The nasal cavity of the buffalo received its blood supply from the sphenopalatine and the external ethmoidal arteries; the former vessel chiefly supplied the respiratory portion of the nasal mucosa, while the latter was distributed to the olfactory region. The greater palatine artery supplied a palatonasal branch in the most extreme oral part of the nasal floor. The nasal vestibule received bronches from both the maxillary labial and infraorbital arteries. The arteries are of the muscular type and presented in addition ot the usual structure of their walls, thin-walled and thick-walled types. Stalked polsters are encountered in the branches of the arterial vessels having walls of the normal thickness. The appearance of the longitudinally arranged smooth muscle fibers found in the intime of some of the subepithelial small arteries and arterioles is suggestive of their epitheloid structure.
