书目名称 | Vascular Pattern in Embryos with Clefts of Primary and Secondary Palate | 编辑 | Edith Frederiks | 视频video | | 丛书名称 | Advances in Anatomy, Embryology and Cell Biology | 图书封面 |  | 描述 | Most embryologists will say after Thoma, that bloodvessels follow the pattern set by organs and have no influence on organs in themselves. If this be true in normal development, what would we find in abnormality? If there be a certain vascular pattern in the developing face, will this pattern be essentially different in cases of clefts of primary and secondary palate? Or is Thomas statement also true here, and are the differences due to following the abnormal formation of the nasal and maxillary parts of the face? Could it be so that the unknown agents responsible for abnormal development act in a time of change in vascular pattern, take their chance just when there is a depletion in vascular supply? Or to the contrary, is there a specific vascular pattern which would allow causal haemato genic agents to reach the areas where we find abnormal development? To answer these questions we will have to compare vascularpatternsinnormal embryos and those with clefts, in stages as near as possible those in which the formation of the clefts takes place, which means for the primary palate the 9-12 mm. stage, for the secondary palate about the 35 mm. stage (Streeters Groups XV-XVII and XXI). | 出版日期 | Conference proceedings 1973 | 关键词 | development; embryo; growth; influence | 版次 | 1 | doi | https://doi.org/10.1007/978-3-642-65535-7 | isbn_softcover | 978-3-540-06128-1 | isbn_ebook | 978-3-642-65535-7Series ISSN 0301-5556 Series E-ISSN 2192-7065 | issn_series | 0301-5556 | copyright | The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer-Verlag GmbH, DE |
