Superficial Ulnar Artery: A Case Report of its Unusual Course Quadros, Lydia Shobha; Bhat, Nandini & D’Souza, Antony Sylvan Abstract After arising from the brachial artery in the cubital fossa the ulnar artery usually passes deep into the superficial flexor muscles of the forearm. In the lower two-thirds, it typically follows a sub-fascial course. In the present case, during a routine undergraduate course dissection of a cadaver, it was found that the ulnar artery arose normally as a terminal branch of the brachial artery in the cubital fossa, followed a sub-fascial course by lying superficial to the flexor muscles then completed the superficial palmar arch in hand. This artery gave only minute muscular branches in the forearm. Moreover, the main branches that usually arise from the ulnar artery were given off by the radial artery. This type of variation is of importance for both the clinicians and surgeons due to its vulnerability to injuries and of academic interest for anatomists. Keywords brachial artery; common interosseous artery; radial artery; superficial palmar arch; superficial ulnar artery
