  • Title: [Micromorphological studies of the blood vessels of the dental pulp of small ruminants].
    Author: Geiger G.
    Journal: Berl Munch Tierarztl Wochenschr; 1992 Dec 01; 105(12):414-23. PubMed ID: 1492836.
    Abstract:
    The blood vascular supply of the dental pulp of 15 domestic sheep of varying age and sex was investigated using light and electron microscopy. The pulp vascular system is showing arterioles with a media of varying thickness and with endothelial cells of variable structure. In the transitional zone between crown and root pulp, the arterioles are taking a typical S- or U-shaped course. The capillary network of the crown pulp is denser and more regular than that in the root pulp. In addition to the capillaries lined by a continuous endothelial tube, there may be others with a typically fenestrated endothelial lining. Specialised vascular structures of the peripheral blood vessels, especially arterio-venous anastomoses as described in man, have not been observed in the sheep.
