Methods 41 normal fetus were selected with gestational age range from 10 to 38 weeks. Maxilla and mandible bones were taken and treated with serial big pieces section, then developing condition of inferior alveolar artery and nerve were observed. 方法选择41例正常受精龄10~38周胎儿标本,取出其上、下颌骨作大块连续切片,采用HE染色观察下颌骨及下牙槽神经血管的发育情况。
Results: Maxilla was supplied mainly by inferior alveolar artery. The periosteum of maxilla was supplied by buccal branches of posterior superior alveolar artery, branches of infraorbital artery and descending palatine artery. 结果:上颌骨主要由上牙槽动脉供血,上颌骨粘骨膜主要由上牙槽后动脉颊支、眶下动脉分支、腭降动脉分支供血;
