Q

Bell’s Palsy

Study These Flashcards
A

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?

Study These Flashcards
A

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

25
Mastication Muscles
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
Temporomandibular joint (TMJ)
-hinge type of synovial joint
27
Articulation of TMJ
- mandibular fossa of temporal bone - mandibular condyle - articular tubercle of temporal bone
28
Clicking of articular disc
piece of fibrocartilage w/in the joint allowing for "better fit" and shock absorption
29
Salivary glands
parotid, submandibular, sublingual
30
Parotid glands
has CN VII, retromandibular v, and external carotid artery
31
Oral region
teeth, palatine, tonsil, pharynx
32
Teeth
deciduous (baby teeth) - 20 , permanent - 32 | incisors, canines, premolars, molars
33
Tooth structure
crown, neck, root, enamel, pulp cavity, dentin, cementum
34
Nerve supply to tooth
maxillary CN N2 | mandibular CN V3
35
Palate
Hard palate | Soft palate
36
Hard palate
palatine and maxilla
37
Soft palate
fibromuscular moveable post against pharynx awhen swallowing CN X
38
Lingual Frenulum
anchors the tongue
39
Deep lingual v
fastest way to the heart
40
Papillae
Vallate Filiform Fungiform
41
Taste buds are what receptors:
chemoreceptors | salivaa helps dissolve food to taste
42
Tongue muscles
Extrinsic: attached ot tongue and somthing else Intriinsic: only attached to tongue (speaking) CN xII
43
Tongue map
General tasting - 1/3 anterior - CN VI Chordatypmpani - 2/3 - CN IX General sensory - 2/3 - CN V3 Motor - everything - CN XII
44
Pharynx
Oropharynx - mouth Nasopharynx - nose Laryngopharynx - larynx
45
Tonils
Palatine- mouth Pharyngeal aka Adenoids - nasopharynx Lingual - tongue Tubal - ear
46
Functions of nose:
olfaction respiration filtration of dust humidification of air
47
External nose
Hyaline cartilage skin CT
48
Ala
sides of nose
49
Anterior nares
nostrils
50
Chonanae
opening of nasopharynx
51
Nasal Septum
bone: perpendicular ethmoid bone and vomer | septal cartilage
52
Nasal Mucosa
Olfactory: smell Respiratory: filtering and humidifying air: NO smell CN I: sensing smell
53
Conchae (turbinates)
lateral aspect (opp of septum) increase in air turbulence means increase in SA Superior (ethmoid), Middle (ethmoid), inferior (separate)
54
Nasal Meatus
grooves beneath the conchae to help with drainage | has superior, middle, and inferior w/ respect to conchae
55
Sinuses
air filled (skull is light) and moistened
56
Maxillary sinuse
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
