Identifying Ulnar Artery and Nerve

The key insight is to identify the ulnar artery as a landmark to locate the ulnar nerve in the forearm. By scanning from the wrist towards the forearm, one can observe the ulnar artery diverging from the ulnar nerve, leaving the nerve by flexicapial naris. Additionally, it is possible to observe an arterial branch swinging from the ulnar artery to bypass the median nerve in the middle of the forearm. This arterial branch variation was highlighted in a publication by Matt Oldman, showcasing the complexity of nerve and artery relationships in the forearm.
