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.
采用腐蚀铸型技术研究了大鼠舌乳头血管网络的三维结构。在扫描电子显微镜（SEM）下观察了这些类型乳头（小锥形丝状乳头、真正的丝状乳头、菌状乳头和轮廓乳头）的微血管铸型。丝状乳头的微血管排列由明确的简单或扭曲的毛细血管环组成。菌状乳头呈圆柱形，有一个中心孔，毛细血管网络赋予整个乳头形状。最后，还检查了椭圆形轮廓乳头的毛细血管床及其特征性网络和小发夹状环。
