Q

Superior meatus receives drainage from

A

Posterior group of ethmoid air cells

17
Q

Sphenoethmoidal recess is found, drainge of, and what is located there

A

Superior to superior concha
Sphenoid sinus
Location of CN1

18
Q

Why have paranasal sinuses?

A

Increase SA
Lighten skull
Resonance for voice

19
Q

Nasolacrimal duct mechanism

A

Tears sweep from superior-lateral and received by puncta…tears then enter lacrimal sac and nasolacrimal duct…these pass into inferior meatus and swept to pharynx

20
Q

Filia olfactoria

A

Pass from nasal mucosa through cribiform plate of ethmoid

21
Q

Shearing of filia olfactoria results in

A

Leaking of CSF

22
Q

Superior alveolar nerve passes through

A

Maxillary sinus

23
Q

Sinus infection of maxillary sinus can result in

A

Pain to superior teeth
