Some segmental morphological and morphometrical features of the intima and media of the aortic wall in Chinchilla lanigera
Abstract
Background: The aim of this study is to describe the morphology, morphometry and ultrastructure of segments of the thoracic and abdominal aorta portions in Chinchilla lanigera. Thickness measurements of the tunica intima and media complex of the aorta were taken. Materials and methods: In all observed specimens, the thickness values for the tunica intima and media complex of the cranial thoracic aorta were significantly higher (mean: 702.19 μm) when compared to the values of other analysed aortic segments (means: 354.18 μm; 243.55 μm). Complex statistical methods were used to assess the differences between various aortic segments. Results and Conclusions: The components of the vessel walls show variations in structure and thickness, presumably due to an adaptation to functional demand.
