肘关节
学习目标
完成本学习单元后，你将学会：
- 列举参与构成肘关节的骨骼。
- 指出肘关节的主要组成结构（包括关节面、韧带、软骨、滑膜和关节囊）。
- 理解肘关节的主要功能和运动。
观看视频
肘关节是位于上肢肱骨远端与前臂近端之间的滑膜屈戍关节，由肱骨、桡骨和尺骨三块骨骼构成。其主要关节位于肱骨远端与尺骨近端之间，同时桡骨近端与肱骨、桡骨近端与尺骨之间也存在关节连结。从功能上看，肘关节作为屈戍关节，仅支持一个平面的运动——即屈和伸。然而，肘关节也能旋后和旋前前臂来辅助手部运动。
本视频教程将为你概述肘关节的相关知识。
进行测验
在看完肘关节的视频后，来进行测试以检验你的知识。
我们的肘关节测验对你来说太简单了吗？或者你需要更多测试题吗？别担心，你可以利用个性化测验来选择测试的主题和难度级别！

现在你可以直观地看到肘关节的各个特征结构，先从外侧和内侧观察肘关节的结构，再从矢状面观察。
