Fissura (embryo)
Fissura in embryologia est divisio cellularum in primo embryone. Zygota multarum specierum circulos cellularum rapidos subeunt auctu magni momenti carente, fasciculum cellularum magnitudine eadem ac magnitudo primi zygoti gignentia. Cellulae variae ex fissura effectae blastomeri appellantur, qui massam compactam morulam appellatam formant. Fissura finitur cum blastula gignatur.
