What is the function of this adaptation? Stomach: The stomach is the most muscular organ of the digestive tract that is located between the esophagus and the small intestine. The stomach has a J-shaped appearance and contains ridges or rugae in its the inner...
The innermost layer of oblique muscle developed later at 16 weeks of gestation. Conclusion: The gastric muscularis mucosa and muscularis externa developed and differentiated sequentially in the human foetuses. The musculature in pyloric region of stomach was more developed and thick than the body and ...
The muscularis externa of the stomach of the coral fish, Chelmon rostratus Cuvier, consists of four discrete layers - an outermost longitudinal layer followed by a circular, an oblique and an innermost layer. The muscle bundles of the oblique layer appear to be surrounded by thin prolongations ...
Muscularis externa: In human fetuses, the circular inner muscle layer has been detected at the 5th week, whereas the outer longitudinal one has been detected at the 8th week (9). Development of the Esophagus and Stomach The gastric mucosal treated with sucralfate after ulceration appears like ...
3.2Muscular layer cells The muscular wall proper consists ofsmooth musclesarranged in an inner circular layer and an outer longitudinal layer. The action of the two layers, organized at appropriate angles to one another, is the basis of theperistaltic contractions. The thinsmooth musclelayer, named...
There are crypts in the base of the folds. Closely, there is a lamina propria and a thick smooth muscle layer, which is placed according to the format of the organ. A dense portion of connective tissue constitutes the serosa, mixed by some smooth muscle cells....
features of 84 muscularis propria (mp) gastric cancers, defined as gastric cancer invading the muscularis propria of the stomach, were reviewed retrospectively, and compared with 267 early gastric cancers (m/sm cancer) and 333 gastric cancers invading beyond the subserosal layer (ss-si cancer)....
In three cases, foci of pale eosinophilia and vacuolation of myocytes were observed. These findings are suggestive of a degenerative and fibrotic abnormality in the outer layer of the tunica muscularis of the large intestinal smooth muscle of some horses with colic....
By electron microscopy dextran-containing vacuoles were conspicuous after 1 h or more. MLC of the subserosal layer and between the circular and longitudinal muscle layers could be distinguished with respect to general appearance, pattern formation, and apparent dextran contents. 展开 年份: 1985 ...
Endoscopic submucosal dissection for treatment of esophageal submucosal tumors originating from the muscularis propria layer The technique of endoscopic submucosal dissection (ESD), which was developed for en bloc resection of large lesions in the stomach, has been widely accepte...
