Descrição
Resumo:The intimal layer of the thoracic and abdominal aortic segments of Cebus apella monkey presented an evident inner elastic lamina. The medial layer of the thoracic aorta segment showed a basic lamellar elastic pattern having a medium average of 23.12 lamellae per analyzed cut sections, which appeared disposed circular and oblique relatively to the aortic lumen. The aortic adventitial layer, at this level, was formed mainly by collagen fibers, irregularly disposed between elastic fibers and smooth muscle cells. The aortic abdominal portion, in this monkey, at the suprarenal level presented a medium number of 19.12 elastic lamellae which showed a relatively disorganized and broken up pattern. At the infrarenal level the aortic medium layer showed a medium average of 11.75 elastic lamellae and next to the emission of the internal iliac arteries it was found only a middle average of 8.37 elastic lamellae intermingled with smooth muscle cells and collagen fibers whose concentration seemed to be increased next to the adventitial layer. The external elastic lamina was only present in the more distal aortic segment near to the emission of the internal iliac arteries.
