  • Title: Three-dimensional angioarchitecture of tongue corrosion casts from normal young rats.
    Author: Makiyama MC, Watanabe IS, Mizusaki CI, Konig Júnior B.
    Journal: Ann Anat; 1998 Aug; 180(4):327-30. PubMed ID: 9728273.
    Abstract:
    The three-dimensional architecture of the vascular network of the rat's lingual papillae has been studied employing the corrosive resin cast technique. The casts of the microvasculature of these types of papillae (the small conical filiform, true filiform, fungiform and vallate papillae) have been observed under scanning electron microscopy (SEM). The microvascular arrangements of the filiform papillae consist of well-defined simple or twisted capillary loops. The fungiform papillae have a cylindrical form with a central hole, and the capillary network gives shape to the whole papilla. Finally, the capillary bed of the oval-shaped vallate papilla with its characteristic network and small hairpin-like loops was also examined.
