when infxn gets into the CN VII cxing drooping of the face

d/t leaving the window (cold air on face) open

24
Q

What are the trigeminal nerves?

A

Chief sensory motor nerve on face:
V1- opthalmic division; sensory
V2- maxillary division; sensory
V3- mandibular division; sensory and motor

25
Q

Mastication Muscles

A

CN V3
Temporalis m. - elevate the mandible
Masseter m. -elevate the mandible and side-to-side
Medial pterygoid m - elevate the mandible and side to side by slinging the ramus
Lateral pterygoid m. - depresses mandible and protrudes the mandible

26
Q

Temporomandibular joint (TMJ)

A

-hinge type of synovial joint

27
Q

Articulation of TMJ

A
  • mandibular fossa of temporal bone
  • mandibular condyle
  • articular tubercle of temporal bone
28
Q

Clicking of articular disc

A

piece of fibrocartilage w/in the joint allowing for “better fit” and shock absorption

29

A

has CN VII, retromandibular v, and external carotid artery

31

A

deciduous (baby teeth) - 20 , permanent - 32

incisors, canines, premolars, molars

33

36
Q

Hard palate

A

palatine and maxilla

37
Q

Soft palate

A

fibromuscular
moveable
post against pharynx awhen swallowing
CN X

38
Q

Lingual Frenulum

A

anchors the tongue

39
Q

Deep lingual v

A

fastest way to the heart

40
Q

Papillae

A

Vallate
Filiform
Fungiform

41
Q

Taste buds are what receptors:

A

chemoreceptors

salivaa helps dissolve food to taste

42
Q

Tongue muscles

A

Extrinsic: attached ot tongue and somthing else
Intriinsic: only attached to tongue (speaking)
CN xII

43
Q

Tongue map

A

General tasting - 1/3 anterior - CN VI
Chordatypmpani - 2/3 - CN IX
General sensory - 2/3 - CN V3
Motor - everything - CN XII

44
Q

Pharynx

A

Oropharynx - mouth
Nasopharynx - nose
Laryngopharynx - larynx

45
Q

Tonils

A

Palatine- mouth
Pharyngeal aka Adenoids - nasopharynx
Lingual - tongue
Tubal - ear

46
Q

Functions of nose:

A

olfaction
respiration
filtration of dust
humidification of air

47
Q

External nose

A

Hyaline cartilage
skin
CT

48
Q

Ala

A

sides of nose

49
Q

Anterior nares

A

nostrils

50
Q

Chonanae

A

opening of nasopharynx

51
Q

Nasal Septum

A

bone: perpendicular ethmoid bone and vomer

septal cartilage

52
Q

Nasal Mucosa

A

Olfactory: smell
Respiratory: filtering and humidifying air: NO smell
CN I: sensing smell

53
Q

Conchae (turbinates)

A

lateral aspect (opp of septum)
increase in air turbulence means increase in SA
Superior (ethmoid), Middle (ethmoid), inferior (separate)

54
Q

Nasal Meatus

A

grooves beneath the conchae to help with drainage

has superior, middle, and inferior w/ respect to conchae

55
Q

Sinuses

A

air filled (skull is light) and moistened

56
Q

Maxillary sinuse

A

most common to get infxn d/t to the aperture is at top of sinus
close to maxillary teeth so if sinus gets too bad from infxn, molars might hurt
