AI Article Synopsis
- Variations in the arterial patterns of the upper limb are common during dissections, but encountering multiple variations in one limb is rare.
- Dissection of an amputated female upper limb revealed that the superficial brachial artery becomes the radial artery, while the deep brachial artery turns into the ulnar artery in the forearm.
- Additionally, a median artery arises from the ulnar artery and has a unique branching pattern, while the median nerve forms a loop around the median artery before bifurcating near the wrist.
Article Abstract
Variations in the arterial pattern of the upper limb are frequently encountered during dissection of the human body. However, multiple variations in one limb are infrequently encountered. Dissection of the left amputated upper limb, 15 cm above the intercondyler line, of a female cadaver revealed the following variations. 1. The superficial brachial artery descends behind the bicepital apneurosis and continues as the radial artery. 2. The deep (definitive) brachial artery continues in the forearm as the ulnar artery under the superficial flexor muscles of the forearm. 3. The median artery arises from the ulnar artery 5 cm below the intercondyler line and continues deep to the flexor retinaculum. 4. The median artery terminates in the hand as princeps pollicis and radials indicis arteries. 5. The median nerve forms a loop surrounding the median artery 4 cm below the intercondyler line and bifurcates 2 cm above the flexor retinaculum.
