Summary edit
| Description |
Deutsch: Diese Grafik zeigt die Unterschiede der beiden Haupttypen von Cölomaten: der Protostomia (Mollusken, Annelida, Arthropoden, ...) und Deuterostomia (Stachelhäuter, Wirbeltiere , ...). Diese Gruppen unterscheiden sich in der frühen Entwicklung durch mehrere Merkmale: die Teilung der Blastula der Deuterostomia wird "Radiärfurchung" genannt, da sie achsensymmetrisch geschieht. Bei den Protostomia wird die Spaltung "Spiralfurchung" genannt, da die Zellteilungen schräg zur polaren Hauptachse ausgerichtet sind. Während der Gastrulation entwickeln die Embryonen der Protostomia zuerst den Mund während später der Blastoporus den Anus bildet. Dies gilt in umgekehrter Reihenfolge für die Deuterostomia.
English: This diagram is showing the difference of the two major types of coelomates: the protostomes (molluscs, annelids, arthropods, ...) and deuterostomes (echinoderms, vertebrates, ...). These groups differ in several characteristics of early development; In deuterostomes blastula divisions is called "radial cleavage" because it occurs parallel or perpendicular to the major polar axis. In protostomes the cleavage is called "spiral" because division planes are oriented obliquely to the polar major axis. During gastrulation, protostomes embryos' mouth was given first by the blastopore while the anus was formed later and vice versa for the deuterostomes. |
