Study Notes

Topographic Anatomy of the Upper Extremity

The upper extremity is divided into regions for studying its anatomy
These regions include the scapular, axillary, deltoid, intertubercular, subclavian, infra-supraclavicular, brachial, posterior brachial, and anterior cubital regions
The elbow joint, forearm, and hand regions are also studied for complete anatomy
The hand is divided into the palm and the dorsal region
