study study study

Hey guys... i just have a few clarification questions that im a bit confused with.
OK
I have been working through the revision workbook and with Q4. it is asking about enamel rods and interrods. I think i understand the structure etc but is someone able to give me a general overview of this structure etc just to help me understand.

With aprismatic enamel i know it is in deciduous teeth and in the mostinner and most outer layer of permanent teeth. but is that in all permanent teth or is is just those that are forming early?? I think it is in all but not sure.

Age changes that occur in pulp. I just said it becomes smaller with age(more dentine etc) and also that there is a decrese in the number of cells which affects ability to do stuff properly(lol im too lazy to type the explainations :D ) but are there any others that i have missed.

Thanks guys. Happy Revision. :D

Facial/Masticatory Muscle Question

Hey guys,

"Section B" of exam "Osteo-Myology of the Head & Neck" trial exam, question 2 seems to have got me confused. As far as i know, there are only 4 masticatory muscles, and 8 facial expression.

Which 2 other muscles are INVOLVED in the masticatory process?

(Fairly sure, in question one, i've already used all 4 masticatory muscles, so i cannot use them again)

-I'm thinking obicularis oris? keeps the lips pursed so that food does not fall out..

-Buccinator? - Helps pull the mouth laterally..

Thanks.
