14

a 62 year old female visits the family physician with complaints of right sided hearing loss, ringing in the right ear (tinnitus), numbness over the right half of her face, and dizziness. the physician diagnoses her w/ an acoustic schwannoma that is occluding her right internal acoustic meatus. the internal acoustic meatus pierces the posterior surfaces of the petrous part of the temporal bone. the internal acoustic meatus transmits what two nerves?

16

which foramina appears as a small round radioLUCENT area on the mandibular PREMOLAR and can be confused with a periapical abscess if not recognized correctly

mental foramen

17

the mandibular foramen leads into the _ canal, which opens on the lateral surface of the body of the mandible at the _

mandibular
mental foramen

19

in relationship to the occlusal plane of the mandibular molars, the mandibular foramen is located _ the occlusal plane and _ to the molars

at or slightly above

posterior to the molars

20

the lingual is a tongue shaped projection of bone that serves as the attachment for the

sphenomandibular ligament

21

what 3 things travel thru the mandibular foramen?
