11. A Systematic Study of the Main Arteries in the Region of the Heart. Aves: Piciformes*

Abstract

Summary. Eight species of Ramphastidæ, 11 species of Capitonidæ, six species of Bucconidæ, two species of Indicatoridæ, and 45 species of Picidæ were studied, and descriptions with diagrams of the main arteries in the region of the neck and thorax prepared. Suggestive differences in the arrangement‐patterns of the arteries were recorded with reference to the basic Order pattern and the Family variation. Presence of the ligamentous vestiges of the left radix aortæ, right ductus botalli, and right ductus caroticus were noted along with the presence of a patent ductus caroticus in Dryobates v. villosus. Possible phyletic relationships between other orders of birds were indicated by the arterial arrangement. All families of the Picidæ were found to be “laevo‐carotidinæ” whereas in the Coraciiformes some families were “lævo‐carotidinæ” while others were “bicarotidinæ normales.” The ductus shawi was shown to be the functionally modified ductus caroticus and was found to be a vessel which results from anastomoses with other smaller arteries which form in situ during middle to late embryogeny. The tendency for a large number of anastomoses of major embryonic vessels, with a few pertinent examples, was noted.

“…neste sentido, a realização de pesquisas sobre a morfologia dos órgãos e seus sistemas vasculares nas diferentes espécies animais, incluindo o homem, pode apontar evidências significantes para a confirmação de semelhanças, ou relacionar diferenças anatômicas importantes entre estes grupos, contribuindo para o desenvolvimento de novas linhas de pesquisa (GLEnnY, 1945;BOMBOnATO et al, 2001;SAnTAnA et al, 2008).…”

Arterial system of the Herring gull (Larus argentatus)

“…Arterial systems in the order Charadriiformes have not been thoroughly investigated. Garrod (1873), Beddard (1898), and Glenny (1947Glenny ( , l948,1952a found that the Charadriiformes are fundamentally "bicarotidinae normales", that is, both internal carotids enter the hypapophysial canal and pass anteriorly to the head without fusing. In the family Alcidae, however, Plautus alle and some specimens of Synthliboramphus antiquus exhibit the "laevocarotidinae normales" condition, in which the left internal carotid alone enters * Present address: Dept.…”

“…The arterial system of the Herring gull has not been extensively investigated. Glenny (1947), in his study of the major arteries of the neck and thorax of birds, described the main arteries of the heart region in the Herring gull. His results differ in certain details from those obtained in the present study.…”

“…Desta forma, justifica-se a realização de estudos específicos relacionados à distribuição vascular em órgãos e sistemas, principalmente no aspecto comparativo, pois, como relatado por Glenny (1945), as artérias e seus ramos, nas mais variadas ordenações, aparecem como evidência significante para a confirmação de semelhanças e relações entre diferentes grupos de animais.…”
