Hey guys i just have a question in relation to embryology..
on pg44 of our embryology text it says that the maxillary process and mid-face formation is during the fourth week of prenatal development (within the embryonic period) but in our lecture notes from wk 11 development of the face and neck; it says during the 5th week? (its on the slide titled 4th-5th week: maxillary processes & mid-face formation)
I think its the 4th week but i just wanted to see what you guys think!
Your help would be greatly appreciated!

hey ok so i had da look at what you are saying. and i agree i think it is 4th week but i think that the lect notes say 4th-5th week coz its allowing for variation etc. Basically i would say that mandibular adn maxilla/midface occurs in 4th week however the mandibular formation occurs first(ie maxilla forms from mandible) and so this may mean that maxilla formatin doesn't begin until the 5th week..
thats kinda what i got out of those.hope it makes sense. And i hope its right??hopefully someone else jumps on and either agress or diagrees with this. :D
Hi all
Nicole is right - these things are somewhat continuous so as long as you know the period of prenatal dev (eg early embryonic etc), that will be fine. It's more important to understand the correct sequence.
