The development of the omental bursa and its forming organs has been studied in 53 embryos, 2.8--30 mm parietococcygeal length. As the data obtained demonstrate, isolation of the omental bursa anlage from the right pleuroperitoneal canal of the coelomic cavity results from the appearance of an additional right pulmonary mesentery and a fold of the inferior vena cava. The pulmonary-esophageal part of the anlage is the first to form, and then the gastrohepatic one. The latter gives origin to the omental bursa proper and the antrum. Both parts of the anlage participate in the formation of the superior omental recess. During the human embryogenesis the anterior intestinal derivates undergo spiralization which is realized by two phases--the first, at the level of the inferior third of the stomach and the forming superior horizontal part of the duodenum, and the second--at the level of the superior third of the developing stomach and the esophageal peritoneal part. The spiralization is ensured by a predominant growth of the presumptive greater curvature of the stomach and by the presence of fixative zones in the area of the transversal septa and the future superior horizontal part of the duodenum. Early stages in the stomach development, dynamics of specific interrelations between the organ's margins of the ventral and dorsal mesenterii in embryos at different ages, reflect the phases of spiralization and witness against mechanical furn over of the stomach around the vertical and sagittal axes.
对53例顶臀长2.8 - 30毫米的胚胎的网膜囊及其形成器官的发育进行了研究。所获数据表明，网膜囊原基从体腔的右胸膜腹膜管分离是由于额外的右肺系膜和下腔静脉皱襞的出现。原基的肺食管部分最先形成，然后是胃肝部分。后者产生了网膜囊本身和胃窦。原基的两个部分都参与了网膜上隐窝的形成。在人类胚胎发育过程中，前肠衍生物会发生螺旋化，这通过两个阶段实现——第一阶段，在胃下三分之一和十二指肠正在形成的上水平部分的层面；第二阶段，在发育中的胃上三分之一和食管腹膜部分的层面。螺旋化是由胃假定的大弯的主要生长以及在横隔和十二指肠未来上水平部分区域存在固定区来确保的。胃发育的早期阶段，不同年龄胚胎中腹侧和背侧肠系膜器官边缘之间特定相互关系的动态变化，反映了螺旋化阶段，并反驳了胃围绕垂直轴和矢状轴的机械翻转。
