Embryonic Smell Development

Week	Carnegie Stage	Event
week 4 GA 6	11	nasal epiblastic thickening appears
	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
week 8 GA 10	21	structure of the olfactory bulb is evident.
