The blood vascular system of the stomach wall in the cat The results of 19 vascular-injections of the stomach wall in the cat are given. The arterial supply to the parietal surface is derived principally from the left gastric artery, that of the visceral surface from the short gastric branches of the splenic artery. Thus the arterial distribution is similar to the venous drainage. The blood supply of the tunica serosa and the tunica muscularis in the fornix and body regions arises from a common subserosal and muscular plexus. In the pyloric canal the blood supply arises from separate subserosal and intermuscular plexus. The submucosal plexus consists of both arteries and veins: from this, mucosal arteries ascend to a subglandular plexus and thence arterioles supply the capillary plexus of the lamina propria. Venules return the blood through collecting veins to a basal venous plexus, thence through mucosal veins to the submucosal plexus.  相似文献

It was shown both light and electronmicroscopically on cartilage of elbow and hock joints of calves and pigs that during formation of synovial fossae, fibrocytes and covering cells of the synovial layer can arise from chondrocytes.  相似文献
