查询词典 anterior intestine

The digestive tract was distinctively divided into buccopharyngeal cavity, esophagus, stomach, anterior intestine and posterior intestine at 1-2 days after hatching coinciding with the time of first feeding. The stomach was divided into cardiac, fundic and pyloric regions. The gall bladder was obvious.

孵出后1-2 d的仔鱼，消化系统已发育较完备，消化道分化为口咽腔、食道、胃、前肠和后肠，胃分化为贲门部、基底部和幽门部，胆囊明显，仔鱼开口摄食而进入混合营养阶段。

Gastric glands distributed in fundic regions at 5-8 DAH. At this stage, supranuclear vacuoles occurred in the anterior intestine and eosinophilic granules occurred in the posterior intestine. The volume of the liver increased. Zymogen granules were seen in the exocrine pancreas and the langerhans was obvious. From 21 DAH to 33 DAH, the digestive system developed to be perfect.

孵出后5-8 d的仔鱼，胃基底部的粘膜上皮下出现胃腺，前肠粘膜层中出现核上空泡，后肠粘膜层中出现嗜曙红颗粒，肝脏体积增大，在胰脏的腺泡中出现大量的嗜酸性酶原颗粒，胰岛明显。

Distribution of gregarines was more concentrated in the anterior and middle parts of the intestine than in the posterior part.

簇虫在马陆肠道中并非平均分布，出现於前段与中段的数目远远大於后段。

With the development of embryo, Myf5 expression decreased gradually in somites in the anterior region, but remained strong in the newly formed somites; After 30 somites formed, MyoD expression decreased in the somites except the caudal somites. At the hatching stage, MyoD and Myf5 were expressed in head muscle cells and fin muscle cells. In the growing fish, Myf5 was expressed in the skeletal muscle and intestine, and in adult flounder, Myf5 was only expressed in muscle. In the growing fish and adult fish, MyoD was only expressed in muscle.

在胚胎发育早期，Myf5在近轴中胚层中表达，体节发生过程中，Myf5在体节中表达，MyoD基因最早在分节板的体节前细胞中表达，随后在近轴细胞、体节中表达；随着胚胎的发育，Myf5在成熟体节中表达量降低，在新生体节中表达较强；MyoD自30个体节时期后只在新生的尾部体节中表达，在成熟的体节中表达量降低；在孵化期，MyoD和Myf5在头部及鳍的肌肉、尾部的体节中表达；生长期的牙鲆中，Myf5在骨骼肌和肠中表达，成体牙鲆中，Myf5只在肌肉中表达；生长期的牙鲆及成体牙鲆中，MyoD只在肌肉组织中表达。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
