A and B. Light microscopy of total nerve fibers in a normal (A) and haemangiomatous (B) artery of the face stained using Bodian's method. The adventitia was separated from other layers of the artery wall and stretched on a slice. As can be seen, there are fewer nerve fibers in the haemangiomatous artery (B) than in the normal artery (A) (magnification 400×; bar 100 μm).
