Vascular network in papillae of dog oral mucosa using corrosive resin casts with scanning electron microscopy

摘要: The purpose of this study was to undertake a three-dimensional analysis the vascular network lamina propria in gingiva, alveolar mucosa, buccal palate, and lingual mucosa dog. Using corrosive resin casting technique, casts were prepared examined by scanning electron microscopy. In oral larger arteries submucosa divide into smaller branches that enter propria. These form one or more layers vessels at base papillae propria, so-called subpapillary network. Here again subepithelial capillary configuration loops within each papilla is determined shape papilla. characteristic resembles hairpin. are complex than found elsewhere mucosa. posterior portion hard soft tongue contain many venous valves.
