问题使声带外展、声门变大的肌肉是

选项 A．环杓侧肌 B．环杓后肌 C．环甲肌 D．甲杓肌 E．杓肌

答案 B

解析：环杓后肌起自环状软骨板背面的浅凹，止于杓状软骨肌突后面。该肌收缩时使杓状软骨向外、稍向上，使声带外展，声门变大。

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.
