which of the following bones form the roof of the orbit?
1- zygomatic
2- maxilla
3- palatine
4- sphenoid
5- frontal


u r rite its formed by both frontal and sphenois(lesser wing) but major bulk is formed by frontal, posteriorly its formed by lesser wing of sphenoid.

hope tht helps

[vibhakar]

mesiobuccal cusp passes thro lingual groove.

 

[vibhakar]

active transport occur in all except bowmwns capsue i guess.
here simple diffusion occurs..
pct not sure

 

[vibhakar]

risk facor for ovarian cancer i think is oral contraceptive use..
