Resumo

Structural features of segmental parts of the aorta of rabbit were studied by light, scanning and transmission electron microscospies. The variabilities in architectural composition and thicker of the vascular coats as well as in vascular diameters at the ascendent (T2-3 level), thoracic (T6-7 level) and abdominal (L5-6 level) segments of the aorta were verified. Morphological features such as presence of intimal folds; occurrence of medial myo-elastic connections with segmental variations in the number of elastic lamellae, whose relative number was major in the ascendent and thoracic parts relatively to the abdominal part, and predominance of a network of stromal elements (connective fibers) in the adventitia were characterized. Also, the morphological findings were discussed at histophysiological base, because small but significative segmental differences were observed in the mural aortic structure of the rabbit (AU)
