1 . Vascular area (area vasculosa) from upper surface after three days of incubation; a â€” vascular area; b â€” transparent place (area pelludica) ; c â€” embryo; d â€” heart; e â€” lateral yolk veins; f â€” descending vein; k â€” boundary vein.
2. Lower surface of the vascular area and on it the vesicle or false amnion; a â€” lower surface of the vascular area; b â€” transparent place; c â€” false amnion and on it (from c to d) cephalic branch; di â€” middle part of it; i to b â€” caudal membrane; d â€” cardiac fossa, from d to i, commissure; i â€” lower fossa; e â€” lateral veins; f â€” descending vein; g â€” ascending vein; h â€” boundary vein.
3. Upper surface of the vascular area in living embryo of three and a half days of incubation; a â€” embryo; b â€” fossa, which it forms in yolk; c â€” origin of yolk veins; d â€” their lower branches; f â€” middle branches; g â€” branching of the upper branches; h â€” ascending vein; k â€” its branches; i â€” descending vein; 1 â€” terminal vein.
4. Vascular area in living condition; a â€” chamber of heart; from above, bulb of aorta, from downwards, auricle of the heart; b â€” aorta; c â€” hollow vein; d â€” ascending vein; e â€” descending vein.
5. Transparent place in the embryo from lower surface, under microscope, 54 hours of incubation; a â€” transparent place; b â€” cephalic branch; c â€” part of the embryo above the cardiac fossa; d â€” anterior part of the head;
e â€” heart; f â€” first rudiment of the true amnion; g â€” ascending vein; h â€” origin of cephalic branch; i â€” swollen edge of the ventricle opening; k â€” opening of the stomach still is not closed, but has narrowed; 1 â€” abdominal folds; m â€” intestinal folds; n â€” rudiments of vertebrae; o â€” end of vertebrae; p â€” the beginning of formation of amnion opening; q â€” spinal cord; r â€” marked lateral parts of the vesicle; s â€” traces of retiform, derived from red blood, vessels; vâ€” -first rudiment of the caudal membrane.
6. Part of lower surface of the vascular area with the transparent place and embryo, after two days of incubation.
a - the transparent place; b â€” cephalic branch; c â€” upper, swollen region of the lateral part of the vesicle; d â€” lower, still not swollen part; e â€” part of the embryo over the cardiac fossa; f â€” heart; g â€” occiput; h â€” anterior part of the head; i â€” edge of the cardiac fossa; k â€” left abdominal fold; 1 â€” right lower abdominal fold; m â€” internal intestinal fold; n â€” right intestinal fold; oâ€” spinal cord; pâ€” cavity of the intestinal canal; q, r â€” lateral deepenings, rudiments of cavity of the body; from s to t â€” rudiment of caudal membrane; s â€” united abdominal folds; tâ€” union of the intestinal folds, origin of rectum; u â€” slightly bending end of the spinal chord; wâ€” ascending vein; x â€” its branches; yâ€” right lateral vein; z â€” left lateral vein.
7. Part of the vascular area, containing the embryo, covered by the false amnion, after 60 hours of incubation, a â€” immovable false amnion; b â€” cephalic branch; c â€” lateral parts of the vesicle; d â€” caudal membrane; e, f, i, g â€” embryo, translucent through the vesicle; f â€” occiput; g â€” protuberance of right leg; h â€” rudiment of tailbone; i â€” protuberance of left wing; k â€” cardiac fossa; 1 â€” commissure; m â€” lower fossa; n â€” fold of commissure; o â€” opening between abdominal and intestinal folds; pâ€” fold of lower fossa; q â€” ascending vein; r â€” its branches; sâ€” - vein associated with the ascending; t â€” its branches; u â€” descending vein; x â€” abdominal fold; y â€” area formed by the union of trunk folds.
