  • Title: [Microangioarchitecture of the mucosa of the antrum pyloricum in rabbit].
    Author: Jackowiak H.
    Journal: Anat Histol Embryol; 1996 Sep; 25(3):155-9. PubMed ID: 9027243.
    Abstract:
    Microangioarchitecture of the mucosa of the Antrum pyloricum in rabbit was studied by optical and scanning electron microscopy. Passing the lamina muscularis mucosae, arteries of the submucosa reach the lamina propria and branch in to the terminal arteries forming a subglandular network. From these vessels, two capillary nets arise. The first forms a capillary skein around the base of the glands, while the second ascends along the tubuli, moving upwards to the surface along the glandular tubuli. These ascending capillaries also arise directly from the subglandular arterioles of the lamina propria, as well as from capillaries of the basal parts of the glandular tubuli. Subepithelial capillaries form arcuate loops with 2-3 venules or collecting venules, which run into the venous net in the basal region of the lamina propria. Numerous horizontal interconnections exist between the collecting venules but arteriovenous anastomosis in the mucosa was not observed.
