本研究应用手术显微镜和扫描电镜观察了人舌粘膜的微血管构筑。舌深动脉长支和舌背动脉终支在舌粘膜下形成一完整的致密动脉网,跨越界沟和舌正中线,成为一整体。由动脉网发出微动脉支进入舌粘膜内,形成粘膜内的毛细血管网和各种乳头毛细血管丛。另外,还讨论了舌粘膜下馓血管构筑和舌瓣设计与临床舌诊的关系。 In this study, the use of surgical microscope and scanning electron microscopy of human tongue mucosa of the microvascular architecture. The long branches of the deep veins of the tongue and the terminal branches of the dorsal tongue of the tongue form a complete dense arterial network under the lingual mucosa that crosses the midline between the ditch and the tongue as a whole. Artery network issued by the arteriole branches into the tongue mucosa, the formation of the capillary network within the mucosa and a variety of papillary capillary plexus. In addition, the relationship between tongue submucosal vascular architecture and tongue design and clinical tongue diagnosis was also discussed.
