n.漿膜；絨毛膜

Our gut strings are from a Indian craftsman using only mutton serosa. 我們的羊腸弦由印度工匠，僅使用羊漿膜制作而成。

Before ovulation and after ovalation, the change of serosa is not distinct. 產(chǎn)卵前和產(chǎn)卵后漿膜層無明顯變化，產(chǎn)卵時(shí)厚度明顯變薄。

The collagen in the serosa is made up of a triple helix molecular structure. 絨毛膜上的膠原組成了三角形的落選分子結(jié)構(gòu)。
