Angioarchitectural arrangements in corrosion casts of the tongue of young malnourished rats

Casts of the microvascular of three types of lingual papillae have been investigated by scanning electron microscopy (SEM) employing the corrosive resin cast technique. The microvascular arrangements of the filiform papillae exhibit both a simple and a twisted capillary loops. The fungiform papillae which are formed by capillary network resembles a cylinder with a central hole on it. At a high magnification, the venulaeexhibit nuclear imprint of the endothelial cells. The data presented in this study show the general arrangement and angioarchitecture of the lingual papillae in rats on a protein-free diet.
