Nasal Cavity Flashcards

1
Q

3 components to the nasal septum
Anterior to posterior
And clinical correlate

A

Septal cartilage
Ethmoid(perpendicular plate)
Vomer

Fracture of the noise can fracture the cribiform plate and leak CSF from the nose

Q

Epitaxis

A

17
Q

Where are the roots of maxillary teeth found

A

The floor of the sinus

18
Q

What nerves supply the paranasal air sinus and what else do they supply

A

V2-anterior and posterior superior alveolar nerve and they also supply the maxillary sinus and teeth

19
Q

What makes up the hard palate

A

The maxillary bones and the palatine bones

20
Q

What two processes combine developmentally to form the philtrum

Clinical correlate

A

The medial nasal and the maxillary processes fuse to form the upper lip

Cleft lip

21
Q

What fuses to form the primary palate

A

Anterior and incisive foramen formed by the union of medial nasal processes

22
Q

What fuses to form the secondary palate and its location

A

Posterior to the incisive foramen and foramen by the fusion of the maxillary processes

27
Q

Voluntary stages of swallowing

A
  1. Form bonus, chew, form wad with tongue, palate down by PALATOGLOSSUS
  2. Push bolus back- contract the MYLOHYOID AND STYLOGLOSSUS
28
Q

Involuntary stages of swallowing

A
  1. Elevate the soft palate- contract the TENSOR, LEVATOR, AND STYLOPHARYNGEUS
  2. Down the tube-pharyngeal constrictors pull the larynx forward with the hyoid muscles
29
Q

Location of the palatine tonsils

A

In the oropharynx between he palatoglossal andpalatopharyngeal arches

30
Q

Blood supply to the palatine tonsils

A

Tonsillar branch of the facial artery

31
Q

Lymph supply to the palatine tonsils

A

32
Q

What covers the palatine tonsils

A
