Hi,
Can anybody give me correct answer to these question,i am little bit confused,
Which nerve supplies derrivatives of first brachial arch?
1)facial
2)trigeminal
Mandibular foramen is located (with respect to occlusal plane of molars)
1)at the level of occlusal plane of mandibular molars

2)at or below occlusal plane of mandibular molars
3)above occlusal plane of mandibular molars
coz in released papers anwer is given as 3) and old dental decks also say so.but 2006 dental decks says answer no.2).so what is correct.
