研究了56例舌动脉的构筑。舌动脉起始较集中,舌骨大角可作为寻找动脉的标志。由于舌动脉入舌的位置较恒定而浅,易于显露,并与舌下神经和舌静脉有稳定的关系,因而可作为受区动脉。舌动脉干各段的弯曲情况,与舌的不同部分的活动度相适应。舌深动脉有两种类型的分支;短支主要供应舌肌;长支形成粘膜下动脉网,供应粘膜。舌肌内的细微动脉沿肌纤维迂曲走行,吻合丰富,但不越舌正中隔;粘膜下动脉网跨越正中线成为一整体。粘膜的血液直接来自动脉干的分支,吻合很丰富。联系舌的结构、功能及临床应用,讨论了舌血管构筑的特点。
56 cases of lingual arteries were studied. Tongue artery starting more concentrated, the big horn can be used as a sign of looking for arteries. Tongue into the tongue because the tongue position is relatively constant and shallow, easy to reveal, and with the hypoglossal nerve and tongue veins have a stable relationship, which can be used as the affected area arteries. The flexion of the segments of the lingual arteries correlates with the mobility of different parts of the tongue. There are two types of branches in the deep arteries of the tongue; the short branches supply mainly the lingual muscle; the long branches form the submucosal arterial network, supplying mucous membranes. Fine arteries in the tongue muscle along the tortuous line of muscle fibers, consistent anastomosis, but not more tongue is septum; submucosal artery network across the midline as a whole. Mucosal blood directly from the branch of arterial stem, anastomosis is very rich. Tongue tongue structure, function and clinical application, discussed the characteristics of tongue blood vessels.
