Samples were collected from five goats (Capra hircus) from the ascending aorta, aortic arch, descending thoracic aorta, and descending abdominal aorta. These samples were histologically processed to reveal elastic structures in their media. The mean number of elastic lamellae discovered was 91.5 in the mean ascending aorta, 78.5 in the mean aortic arch, 66 in the mean descending thoracic aorta, and 31.7 in the mean descending abdominal aorta. Because they all have a large number of elastic laminae on average, they all fall into the elastic artery category, but not all are typical elastic arteries. Thus, the ascending aorta, the aortic arch, and the descending thoracic aorta contain, on average, in addition to elastic tissue, polymorphous muscle islands, which distinguishes them from typical elastic arteries, which is why we call them particular elastic arteries. The descending abdominal aorta contains no such islands so that it can be classified as a typical elastic artery. The goat aortic segment is the only one comparable in structure to the elastic arteries of humans, which is why we suggest that it is the only one suitable for studying aortic disease in humans.
