问题 单项选择题 B1型题

在平舌骨大角稍下方发自颈外动脉的是()

A.上颌动脉

B.面动脉

C.舌动脉

D.脑膜中动脉

E.甲状腺上动脉

答案

参考答案:E

解析:上颌动脉为供应口腔颌面部的主要动脉,分支较多。分为下颌段、翼肌段、翼腭段。下颌段主要分支有脑膜中动脉、下牙槽动脉,故1题选D;面动脉又称颌外动脉,主要负责面部软组织血液供应,故2题选B;上、下唇动脉属面动脉的分支,两侧上、下唇动脉相互吻合形成动脉环,故3题选B;上颌骨血供极为丰富,接受骨内上牙槽动脉的血供,又接受颊、唇、腭侧黏骨膜等软组织的血供,上牙槽动脉为上颌动脉的分支,故4题选A;甲状腺上动脉一般在舌骨大角稍下方,发自颈外动脉起始部的前内侧壁,故5题选E;舌动脉于甲状腺上动脉起点稍上方,平舌骨大角处,故6题选C。
