Vitreous Body (Corpus vitreum). 



In an eyeball no longer fresh, one that has been kept for 

 from one to four days, divide the tunicae of the eye at the 

 equator, reflect the cut edges backward and forward, and, as 

 Anderson Stuart has suggested, allow the " eye-kernel" (corpus 

 vitreum + lens crystallina) to slip out into a vessel filled with 

 clean water. Transfer it for a few minutes to a strong solution 

 of picrocarmin, then wash in water. The membrana hyaloidea, 

 capsula lentis, and zonula ciliaris [Zinni] will be stained red, 

 and their connections are easily visible. 



In the vitreous body study 



(a) Hyaloid canal (canalis hyaloideus) (0. T. canal of Stilling). 



(b) Hyaloid fossa (fossa hyaloidea) (0. T. fossa patellaris). 



(c) Hyaloid membrane (membrana hyaloidea). 



(d) Vitreous stroma (stroma vitreum). 



(e) Vitreous humor (humor vitreus).
