上肢分区
学习目标
你将在本单元中学到：
- 上肢的主要区域划分。
- 用于描述上肢不同部位的重要术语。
观看视频
为了准确定位和诊断各种损伤和疾病，并与其他医生进行有效沟通，每位医疗工作者都需要掌握人体各部位的解剖术语。上肢 upper limb 同样如此，它的前、后区域进一步分为不同亚区。这些区域中包含着丰富的神经血管结构，是重要的手术定位标志。观看下方视频，你将直观地学习上肢各区域的边界与内容。
进行测验
现在你对上肢各区域有了更深入的了解，不妨通过测验来巩固知识。如果你对此胸有成竹，不妨尝试更多人体通用术语相关的个性化测验。

上肢的许多区域还有其他名称，其中一些是它们的同义词，还有一些是它们的亚区域或可互换使用的术语。学习这些术语很重要，因为它们会在解剖学教材、文章、视频和测验中出现。
| 肩部 shoulder region | 三角肌区（为亚区，但也被用作同义词） |
| 腋区 axillary region | 腋窝 |
| 臂部 arm region |
臂区 臂前区 臂后区 |
| 肘部 elbow region |
肘区 肘前区：肘窝 肘后区：肘后窝，鹰嘴区 |
| 前臂部 forearm region |
前臂区 前臂前区 前臂后区 内侧缘：尺侧缘 外侧缘：桡侧缘 |
| 腕部 wrist region |
腕区 腕前区 腕后区 |
| 手部 hand region |
桡侧凹陷：鼻烟窝 手指： 拇指：第1指 示指：第2指 中指：第3指 环指：第4指 小指：第5指 |
想要观察上肢的主要分区，可以参考我们的标注版图谱。请仔细观察上肢各区域的位置、边界和它们的相对关系。
