为阐明中医舌下络脉的实质,采用连续组织切片结合解剖追踪观察了舌腹面粘膜下静脉及肌层血管,并与犬和大白鼠相对照.结果:舌下络脉在舌腹面外带为舌神经伴行静脉及其属支;内带为舌下神经伴行静脉及其属支;舌边细络为舌神经伴行静脉与舌根静脉的属支,它们均分布在粘膜下层近肌层,犬与大白鼠有相同分布.舌静脉有丰富的静脉瓣和瓣窦,有双瓣、单瓣、静脉隔等类型,舌下神经伴行静脉及舌神经伴行静脉中末段尤多,有连续呈葫芦串者. To clarify the essence of TCM hypoglossal veins, we observed the sublingual venous and muscular layer veins by continuous tissue section combined with anatomical follow-up and compared with dogs and rats.Results: Tongue nerves with accompanying veins and their branches; the inner zone with hypoglossal nerve accompanying veins and their branches; lingual fine network for the lingual nerve with vein and the tongue vein branches, they are located in the submucosa near the muscular layer , Dogs and rats have the same distribution.Vaginous vein is rich in venous and valve sinus, a double valve, single valve, venous septum and other types of hypoglossal nerve accompanying vein and lingual nerve with the last part of the vein in particular, A continuous gourd string were.
