Abstract

The segmental structure of the aortic wall at the thoracic and abdominal levels were studied in domestic chicken by light microscopy (LM) and scanning electron microscopy (SEM). Selected histological sections were submitted to histomorphometric studies using image analysis methods. The variables studied were the thickness of the aortic layers in the three segments investigated: ascendant thoracic, descendant thoracic and abdominal parts as well as the tubular diameters and the mean number of elastic lamellae in the medial layer of each analyzed segment. The aortic wall of the chicken had a predominately elastic structure in the thoracic portions, that decrease gradually in relative number of elastic lamellae towards the abdominal aorta in which smooth muscle cells predominated. Vascular diameters decreased gradually to the ascendant aorta from the descendant thoracic portion and to the last from the abdominal aorta.
