问题连接下颌后静脉与翼静脉丛的静脉为

选项

A.面横静脉
B.面深静脉
C.上颌静脉
D.颞浅静脉
E.面总静脉

答案 C

解析翼静脉丛与颅内、外静脉有广泛的交通，向前经面深静脉通入面静脉，向后经上颌静脉通入下颌后静脉。下颌后静脉分为前、后两支，前支与面静脉汇合成面总静脉，后支与耳后静脉汇合成颈外静脉。

错误啦！

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
