From Embryology
| Carnegie Stage | Event |
|---|---|
| 9 | an indication of mesencephalic neural crest |
| 10 | trigeminal, facial, and postotic components |
| 11 | crest-free zones are soon observable in rhombomere 1, 3, and 5 |
| 12 | rhombomeres 6 and 7 neural crest migrate to pharyngeal arch 3 and then rostrad to the truncus arteriosus |
| 13 | nasal crest and the terminalis-vomeronasal complex are last of the cranial crest to appear |
| 9 to 14 | otic vesicle primordium descends |
| Week: | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
