4 公牛眼睛中的毛細血管
這張光學(xué)顯微照片是由斯匹克－沃克爾(Spike Walker)拍攝的。照片拍攝的是一只公牛眼睛睫狀體的毛細血管。這些毛細血管能分泌水狀液。這些液體為眼球晶體和角膜提供了大部分營養(yǎng)成份。
這張圖片是從不同深度拍攝的27張照片合成而得到的，給人以三維圖的效果。為了更突出顯示公牛眼睛睫狀體的毛細血管并更好地進行拍攝，毛細血管中注射了一種不可溶的染料。
This light microscope image by Spike Walker is of blood capillaries in the ciliary body of an ox's eye: the tiny holes that secrete a liquid called aqueous humour are shown. This liquid provides most of the nutrients for the lens and cornea. This image was created from a stack of 27 images taken at different depths and combined to give a three-dimensional appearance. The capillaries have been made visible by injecting an insoluble dye into the artery. (Image: M. I. Walker) [NewScientist]
