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.
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.
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.
Two repetitive structures with different characteristics, 1 in the perineurium and the other in the endoneurium, merge to give the appearance of these bands.
1779 年,Fontana 在周围神经上发现了横向和斜向的带。随后的研究则指出,神经内膜或神经外膜成分是导致这些带的原因。我们的目的是澄清这些相互矛盾的发现。
在大鼠坐骨神经中记录 Fontana 带的反弹。使用计算机辅助设计 (CAD) 软件通过干涉图来对神经进行建模。
体内显微解剖显示,神经外膜中存在独特的黑白相间、紧密排列的带,与神经内膜中广泛间隔、半透明、暗/浅灰色、交错的带不同。这 2 种模式的 CAD 合并生成的图像类似于体内观察到的带。
两种具有不同特征的重复结构,一种位于神经外膜,另一种位于神经内膜,合并后形成这些带的外观。
