Embryology

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!

human Bio... EEEEppppp

Hi all,
just some quick questions... have been studying head and neck stuff and thort i was doing ok unitl i read some of the previous exam questions and realised i couldn't answer any of them :(.
Any way..

1)when it is talking about nerve supply can someone tell me what it means by the type of innervation? coz i thort this meant whether it was afferent or efferent However.. i dont kow what efferent or afferent means in relation to nerve supply.?? any help would be good.

2)what does proprioception mean? i think i know but i just want to double check and i cant find a definition anywhere.?

3) with enous drainage of head and neck- what is the clinical significance of the cavernous sinus and the pterygoid plexus - coz i had basically that the pterygoid plexus means that infections can spread anywhere into the head and neck as there is no valves and no direction etc.
and the clinical significance of the cavernous sinus is that dental infections can spread to the brain through here?????

4) With microbiology- do we need to know about the history of microbiology or was that just put into the notes for "fun" lol.
5) also with micro- what is the germ theory? or does this just help explain kochs postulates.??

Ok thats all for now guys.. but im sure there will be more soon.

Happy Studies.. thanks for the help :D

Junctional Epithelium Attachment :]

Hey guys, could someone please tell me how the junctional epithelium is attached to both the tooth surface and the lamina propria?

thanks!

Epithelial-Connective Tissue Interface

This is the boundary where the two tissues (ET + CT) meet or "mingle".
The epithelial ridges (retae ridges) reach down into the CT and CT papillae (extensions of CT) extend up to the epithilium.
Well i was just wondering if this clinically appears as stippling?
Thanks

<3 Thu huu and nicole. :D

hey guys ok thu huu adn i had a lil study session today and we have a few questions that we were both unsure of and we just wanted to see what other people have said for these.. OK

- are the bones in the skull flat or irregular.. or neither.. ?

- Q9 of the oral histology workbook (draw a tabl of the structural variations of the oral mucosa) is this asking aboutt hemastictatory/lining/specialised mucosa... somethingsimilar to the table on Page 135 of bath balogh coz w weren't sure.

-Q10 of the Oral Hist. workbook... what is everyone drawing for this... I just draw the gingia against the tooth and labelled the JE the sulcular epith. The Oral epith the attached ging.free ging etc.... Is this what it is meant to be or have i interpreted it differently. ??

-What muscles would experience pain in associatin with overuse of the TMJ... We both had different answers and couldn't really jutify any of them :P

-Pre dentine.. is this the same as manytle dentine and circumpulpal dentine?? What is a definition for pre dentine and where is it coz we started confusing ourselves.

-Why is the tongue considered a specialised mucosa?? we had just described the appearance of the tongue and where it is specialised( taste buds) etc but didn't really think this answered the question???

- The periodontla ligament blood supply... Does this have anything to do with the PDL being continuous with the CT of the Gingiva?? but confused..

-Q7(PDL nad alveolar bone) trace the blood supply through the alveolar bone.. we both just had big ?.... where can we find info on this.. what should it be???

Thanks heaps guys
Hope its all good.
C yas Monday . :D

lingual papillae the same as caruncle?
