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.
