• Introduction: In 1779, Fontana identified transverse and oblique bands along peripheral nerves. Subsequent studies pointed alternatively to endoneural or perineural components as the cause. Our aim was to clarify these conflicting findings. Methods: Recoiling of the bands of Fontana was video‐recorded in the rat sciatic nerve. Computer‐assisted design (CAD) software was used to model the nerve by interference figures. Results: In vivo microdissection showed distinctive, black‐and‐white, closely packed bands in the perineurium, which differed from the widely spaced, translucent, dark/pale gray, staggered bands in the endoneurium. CAD merging of these 2 patterns produced images resembling the bands observed in vivo. Conclusions: Two repetitive structures with different characteristics, 1 in the perineurium and the other in the endoneurium, merge to give the appearance of these bands.
