Regions of the upper limb
In this study unit you will learn how to:
- List the main regions of the upper limb.
- Name the important terms used to describe various parts of the upper limb.
Every medical professional needs to know the descriptive terms used for the regions of the whole body in order to localise and diagnose different injuries and diseases, as well as communicate them to other physicians. The same goes for the upper limb, which is divided into several regions on its anterior and posterior aspects. Many of these regions contain various neurovascular structures, which makes them important surgical landmarks. Get a visual of the upper limb regions, their borders and contents by watching the video below.
Take a quiz
Now that you’re more familiar with the regions of the upper limb, test yourself with the following quiz to solidify your knowledge. If you already feel like a pro, try out our custom quiz to get a broader quiz on the general terminology of the body.
Many of the main regions of the upper limb are also known by other names. Some of these represent their synonyms, and some are their subregions or other related terms that may be used interchangeably. It’s important you know these as you will find them in anatomy textbooks, articles, videos and quizzes.
||Deltoid region (subregion, but in some sources used as synonym)|
|Axilla, axillary fossa|
Anterior arm region: anterior brachial region
Posterior arm region: posterior brachial region
Anterior elbow region: anterior cubital region, cubital fossa
Posterior elbow region: posterior cubital region, olecranon region
Anterior forearm: anterior antebrachial region
Posterior forearm: posterior antebrachial region
Medial border : Ulnar border
Lateral border: Radial border
Anterior region: anterior carpal region
Posterior region posterior carpal region
Radial foveola: anatomical snuffbox
Thumb (pollex): 1st digit
