First, the collagen in our folds stiffens and the surrounding elastin fibers atrophy and decay.

首先， 我们褶皱中的胶原蛋白变硬，周围的弹性蛋白纤维萎缩和腐烂。

Reticular tissue is like areolar tissue, but with a woven mess of reticular fibers — rather than collagen and elastin fibers — hence the name.

网状结缔组织类似于蜂窝组织，但是由网状纤维编织而成——而不是胶原蛋白和弹性蛋白纤维——因此得名。

Tissues that have elastin fibers are tissues like the arteries, skin, and lungs, and tissues that have microfibrils but no overlying layer of elastin are like tendons and the ciliary zonules that hold the eye lens in place.

弹性纤维存在于动脉、皮肤、肺等组织，无弹性蛋白但含有微纤丝的组织包括肌腱以及维持晶状体正常位置的睫状带等。

There's a lot of ground substance in here, and the elastin fibers help it snap back into place, while the collagen helps anchor it so you can't, like, snag your skin on a zipper and watch it just fly off.

这里有很多基础物质，弹性蛋白纤维帮助它弹回原位，而胶原蛋白帮助它锚定，所以你不能把你的皮肤卡在拉链上，看着它飞走。

Another vocal development during puberty occurs when the homogenous tissue covering the folds specializes into three distinct functional layers: a central muscle, a layer of stiff collagen wrapped in stretchy elastin fibers, and an outer layer of mucus membrane.

青春期的另一种声音发育发生在覆盖褶皱的同质组织专门分为三个不同的功能层时：中央肌肉、一层包裹在弹性弹性蛋白纤维中的硬胶原蛋白层和外层粘液膜。
