 CONSIDERATION OF THE RECONSTRUCTION OF THE OVUM FROM SECTION 1-160. 



No. of 

 Section. 



Mucous membrane elevation harboring the ovum. 



Without 

 fibrin cover.

Epithelium 

 beneath? 



Present. 



Becoming steadily longer 

 and lies like a worm with 

 its thick end on the right 

 of the ovular elevation. 



Epithelium

 thickness on 

 the fibrin cov-

 like band com- 

 ing from both 

 sides under the 

 fibrin cover. 



Most likely syncytial cells. 



23. 



24 and 25. 



In elongated part, connec- 

 tive tissue arrangement. 

 Leucocytes, and in the 

 club end fibrin only. Be- 

 tween these two parts as 

 well as towards the ovu- 

 lar elevation many red 

 blood cells. 



Epithelium Under the fib- 



varying in rin cover long 



thickness on streaks of epi- 

 the fibrin cov- thelial-like 

 er. cells. 



Close on to these the long 

 stretched syncytial cells with 

 large nuclei reach, which come 

 from the trophoblast. 



The elongated part be- 

 comes more and more or- 

 ganized, the club end is 

 still fibrinous but is al- 

 ready infiltrated with 

 white blood cells. 



Epithelium

The same.

The fibrin cover becomes Epithelium 

 constantly longer and ' varying in 

 has at its right end a but- thickness, 

 ton-like thickening con- 

 taining many red blood cells. The left end 

 a structureless elongation. Therefore only 

 the middle part is organized. 



As in 23. 



27. 



Fibrin cover very much 

 elongated, on the right 

 end knob-shaped, folded 

 like a corpus luteum, in 

 the center of fold, blood 

 cells. The left end sends 

 out an offshoot and be- 

 comes steadily longer.

end of the fibrin cover this band 

 contains a few cells with a dis-

 are seen the large syncytial

 Blood found in fold of 

 knob end. 



At the base of fibrin cover are found syncytial 

 clubs with many nuclei. Close by, an epithe- 

 lial-like band. 



Epithelial-like 

 band to left 

 under fibrin cover. Probably 

 having some connection with the 

 giant syncytial cells.
