上上上(忘了)个礼拜四,生物节,有史以来最爽的一堂,因为,我们要........

切牛眼!!!别紧张,免惊免惊,眼镜戴好来,手汗擦一下,mouse握好来,跟我往下看,没那么geli啦!!!准备好了吗?


别看它酱大团,其实三分之一是肉来的......

光是剔肉就用掉一节了,以为是肉太韧了,结果是.......刀不会利......['''long piak]


剔完肉了,就划破眼角膜,让水状液流出来,要非常‘幼朽’,不然晶体会被挤出来。然后,把眼睛切一半。这次不是刀不利了,是真的很韧!

这是玻璃状液+放射状肌+晶体+虹膜。看起来像蛋,摸起来像果冻。



这是晶体,原本以为会变不透明[因为牛眼已冷藏了几天],没想到放在报纸上,字还是会变大,神奇神奇!!!拿起来透过它看东西[较远的],全都是颠倒的哦!!!![原因请去看课本第12章]不过,他一下就萎缩了。

视网膜。满美的。看得到盲点。

不过手会黑黑的,脉络膜害的。[因为眼球内要保持暗暗暗暗暗,所以就有了这黑黑黑黑黑的黑色素]

眼睑+眼睫毛
*!*我很好奇为什么要先划开眼角膜,再把眼睛切一半,酱会担心把晶体挤出来,又担心切不好。做么不要先切一半,再划开眼角膜?不是更好?我问老师,她又像耳聋酱.....每次都是酱.......我最讨厌人家酱了......我只是要答案,让我知道吧!!!![who knows the reason?pls tell me]
