The nerve of Henlé, a branch of the ulnar nerve in the forearm, is thought to deliver sympathetic innervation to the ulnar artery. Forty cadaver forearms were dissected under magnification. Two distinct patterns of the nerve were found. In the typical pattern, 18 (45%) of 40 extremities, the nerve originates 16 cm proximal to the ulnar styloid, travels distally with the ulnar artery, and frequently, 13 (72%) of 18, branches to pierce the superficial fascia 6 cm proximal to the ulnar styloid and innervate the skin of the distal ulnar forearm. In the atypical pattern (12%), the nerve originates in the distal 8 cm of the forearm and travels briefly with the ulnar artery before branching to the skin. The palmar cutaneous branch of the ulnar nerve was absent in cadavers with the nerve of Henlé and may be a distal variant of that nerve.
亨利神经是前臂尺神经的一个分支，被认为可为尺动脉提供交感神经支配。在放大条件下解剖了40具尸体的前臂。发现了两种不同的神经分布模式。在典型模式中，40个肢体中有18个（45%），该神经起源于尺骨茎突近端16厘米处，与尺动脉一起向远端走行，并且在18个中有13个（72%）经常在尺骨茎突近端6厘米处分支穿透浅筋膜，支配尺骨远端前臂的皮肤。在非典型模式（12%）中，该神经起源于前臂远端8厘米处，在分支至皮肤之前与尺动脉短暂伴行。有亨利神经的尸体中尺神经掌皮支缺失，它可能是该神经的一种远端变异。
