肋间隙的神经血管
学习目标
完成本学习单元后，你将能够：
- 识别供应肋间隙的动脉及其分支。
- 说出引流肋间隙的静脉及其属支的名称。
- 描述肋间隙的神经支配。
浏览图谱
肋间隙是位于相邻肋骨之间的解剖间隙。其内有三层肋间肌以及由肋间血管和神经组成的神经血管束。每个神经血管束位于肋沟内，沿每根肋骨的下缘走行，并经过肋间内肌与肋间最内肌之间的平面。从上到下，它们的排列顺序为静脉、动脉，最后是神经。每条神经、动脉和静脉发出的较小侧副支沿下位肋骨的上缘走行。

进行测验
通过以下测验测试对肋间隙神经血管知识的掌握程度。
小结
| 动脉 |
肋间前动脉： 起自胸廓内动脉（上6个肋间隙）和肌膈动脉（下位肋间隙） 分支：侧副支 肋间后动脉： 起自肋间最大动脉（前2对）和胸主动脉（后9对） 分支：背侧支、侧副支、外侧皮支 |
| 静脉 |
肋间前静脉： 注入胸廓内静脉。 肋间后静脉： 第1对注入头臂静脉 右侧第2~3对汇合成右肋间上静脉注入奇静脉 左侧第2~3对汇合成左肋间上静脉注入左头臂静脉 右侧第4~11对注入奇静脉 左侧第4~8对注入副半奇静脉 左侧第9~11对注入半奇静脉 |
| 神经 |
第1~11对胸神经前支： 即肋间神经 分支：侧副支、外侧皮支、前皮支（肌支） |
