Embryonic Smell Development
Week Carnegie Stage Event

12 nasal field is well outlined
week 5 GA 7 15 continuous cellulovascular strand seen between the nasal groove and the olfactory field
week 6 GA 8 16 vomeronasal groove appears at stage (O'Rahilly 1967).
17 olfactory nerve is organized into two plexuses, lateral and medial, the latter mingled with the terminal-vomeronasal complex.
week 7 GA 9 18 olfactory bulb begins to appear
19 individualization of the olfactory bulb and nuclei. Distinction between olfactory structures and terminal and vomeronasal ones begins to be clear
