问题腭裂整复术中凿断翼钩是为了松弛哪块肌肉的张力

选项 A:舌腭肌 B:腭帆张肌 C:腭帆提肌 D:咽上缩肌 E:咽腭肌

答案 B

解析此题是专业知识概念与理解试题，考查考生对局部解剖及腭裂手术方式的理解。腭帆张肌起源于翼内板和咽鼓管软骨，其肌纤维与翼突钩纤维性粘连。腭裂整复术中凿断翼钩可使腭帆张肌失去张力。腭帆提肌是软腭的最大肌肉，舌腭肌是软腭口腔面最表面的肌肉。

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.
