肘和前臂的神经血管
学习目标
完成本学习单元后，你将学会：
- 认识肘和前臂相关的动脉、静脉和神经。
- 列举它们的主要分支。
- 观察神经血管的走行以及它们与相邻结构的解剖学关系。
观看视频
肘和前臂的血供和神经支配：
- 桡动脉和尺动脉：尺动脉和桡动脉沿前臂内侧和外侧下行，沿途发出分支供应前臂前区和后区。
- 贵要静脉和头静脉：浅静脉系统由头静脉和贵要静脉组成。贵要静脉引流前臂内侧，头静脉负责引流前臂外侧，两者最终汇入腋静脉。深静脉系统包含成对的桡静脉、尺静脉及骨间静脉，分别引流前臂外侧、内侧及中间区域。
- 正中神经、尺神经和桡神经：这些臂丛的终末支发出运动和感觉神经支配肘和前臂。
本视频教程将为你概述肘和前臂的神经血管系统。
进行测验
你能辨认肘和前臂的动脉、静脉和神经吗？试试我们的测验。
你还可以自定义创建自己的专属测验。在下方链接中，你能找到上肢解剖相关的测验选项，包括肌肉、骨骼、韧带和神经血管系统。
