The funiculus umbilicalis in crossbred zebu bovines
Keywords:Funiculus umbilicalis, Bovine, Arteries, Veins.
AbstractIn this study information about the microscopic aspects of the structures that form the funiculus umbilicalis of zebu like cattle was collected. For this purpose, it was used funiculus umbilicalis of 30 fetuses (13 males, 17 females). Both arteries and veins showed wrinkles in the intima layer in their wall constitution, what was more characteristic in the arteries. The medium
layer of arteries and veins showed well developed muscle, characterizing these vessels as muscular type ones. At the initial portion (juxta-fetal portion) the lumen of arteries and veins was almost obliterated, but it enlarged as they got closer to the juxta-placentaria portion of the funiculus umbilicalis. The amount of reticular, elastic and collagen fibers on the vessel wall was compared by the use of specific histological techniques. Some aspects about the alantoid duct were also noticed.
