Q

What runs through cribiform plate?

A

21
Q

What does fracture of the cribiform plate cause?

A

CSF leakage and anosmia

22
Q

Where is the main blood supply to the nasal cavity?

A

o Branches of the Opthalmic Artery
 Branch of the Internal Carotid Artery
o Branches of the Maxillary and Facial Arteries
 Branches of the External Carotid Artery

23
Q

What is the area of the nose with the densest block of capillaries called?

A

Kiesselbach’s area

24
Q

Where do nose bleeds most often occur?

A

Kiesselbach’s area

25
Q

What are twodifferent places nose bleeds can occur, and what are the percentage chance of it happening in each place?

A

Anterior bleed - 90%

Posterior bleed - 10%

26
Q

What artery is responsible for posterior bleeds?

A

Sphenopalatine artery

27
Q

Where do the veins of the nasal cavity drain into?

A

Cavernous sinus
Facial vein
Pteryoid plexus

28
Q

What provides special sensory smell in the nose?

A

Olfactory nerve

29
Q

What provides general sensation to the posteroinferior nasal mucosa?

A

 Maxillary Division of the Trigeminal Nerve (CN V2)

 Nasopalatine Nerve

30
Q

What provides general sensation to anterosuperior nasal mucosa

A

 Opthalmic Division of the Trigeminal Nerve (CN V1)

 Anterior and Posterior Ethmoidal Nerves

31
Q

What provides general sensation to the external nose?

A

 External Nasal Nose (CN V1)

 Infraorbital Nerve (CN V2)

32
Q

What is the epithelium of the respiratory region of the nasal cavity?

A

Pseudostratified columnar ciliated with goblet cells

33
Q

What is the epithelium of the olfactory region of the nasal cavity?

A

Olfactory cells with olfactory receptors

34
Q

What are the paranasal sinuses?

A

air-filled extensions of the respiratory part of the nasal cavity into cranial bones

35
Q

What are the names of the four paranasal sinuses?

A

Frontal, ethmoid, sphenoid and maxilla

36
Q

Where are the frontal sinuses found?

A

between the outer and inner tables of the frontal bone, posterior to the superciliary arches and the root of the nose

37
Q

When are the frontal sinuses usually detectable?

A

By age of 7 years in children

38
Q

Where do the frontal sinuses drain?

A

They each drain through a Frontonasal Duct into the ethmoidal infundibulum, which opens into the semilunar hiatus of the Middle Nasal Recess.

39
Q

What are the ethmodal sinuses?

A

Small invaginations of the mucous membrane of the middle and superior nasal recesses into the Ethmoid bone

40
Q

What are the three ethomoidal sinuses?

A

Anterior ethmoidal cells
Middle ethmoidal cells
Posterior ethmoidal cells

41
Q

Where do anterior ethmoidal cells drain?

A

Ethmoidal infundibulum -> Middle nasal recess

42
Q

Where do the middle ethmoidal cells open into?

A

Middle nasal recess directly

43
Q

Where do the posterior ethmoidal cells open?

A

Directly intot he superior nasal recess

44
Q

Where are the sphenoidal sinuses located?

A

Body and wings of the sphenoid

45
Q

What is the clinical significance of the location of hte sphenoidal sinus?

A

Body is fragile and only thin plates of bone separate the sinuses from important structures (optic nerves and chiasm, pituitary and internal carotid arteries)

46
Q

Where does the sphenoidal sinus drain?

A

Sphenoethmoidal recess

47
Q

Where are the maxillary sinuses found?

A

Bodies of the maxillae

48
Q

Where do the maxillary sinuses drain?

A

The Maxillary Sinuses are the largest of the paranasal sinuses. They occupy the bodies of the Maxillae.
They drain by one or more openings, the Maxillary Ostium (ostia), into the middle nasal recess by way of the semilunar hiatus.
