Q

nasal mucosa

Study These Flashcards
A

lines bulk of cavity
-rich in blood vessels and mucous glands to warm air

olfactory epithelium lines superoposterior part of cavity
-CN I

24
Q

rhinitis

Study These Flashcards
A

inflammation of nasal mucosa

infection spread:

  • anterior cranial fossa via cribriform
  • nasopharynx
  • middle ear via pharyngotympanic tube
  • lacrimal apparatus and conjuctiva via nasolacrimal duct
  • paranasal sinuses
25
sphenoethmoidal recess
area posterior and superior to superior concha | -opening for sphenoid sinus
26
superior nasal meatus
beneath superior concha | -opening for posterior ethmoidal sinus
27
middle nasal meatus
beneath middle concha - bulla ethmoidalis and semilunar hiatus - opening for frontal, maxillar, A/M ethmoidal air cells middle ethmoid - ethmoidalis bulla
28
inferior nasal meatus
beneath inferior concha | -openings for nasolacrimal duct
29
frontal sinus drainage
frontonasal duct semilunar hiatus middle nasal meatus
30
maxillary sinus drainage
semilunar hiatus | middle nasal meatus
31
anterior ethmoid air cell drainage
semilunar hiatus | middle nasal meatus
32
middle ethmoid air cell drainage
ethmoid bulla | middle nasal meatus
33
posterior ethmoid air cell drainage
superior nasal meatus
34
nasolacrimal duct drainage
inferior nasal meatus
35
blood supply from internal carotid a
anterior and posterior ethmoidal arteries -branches of opthalmic a
36
blood supply from external carotid a
sphenopalatine a greater palatine a facial a
37
kisselbach area
anastomose between: - greater palatine a - anterior ethmoidal a - sphenopalatine a - facial a NO POSTERIOR ETHMOIDAL** anterior portion of nasal septum -compress here to stop nose bleed
38
major artery to nasal cavity
sphenopalatine a chronic nosebleeds involve this often**
39
olfactory nerve
SVA CN I bipolar neurons in superior nasal cavity epithelium neuron processes through cribriform plate -synapse olfactory bulb
40
olfactory bulb
extension of forebrain (telencephalon) | -CN I synapse directly with forebrain**
41
ophthalmic nerve
V1 - GSA to nose and sinuses branch of trigeminal enters orbit via superior orbital fissure
42
branches of ophthalmic nerve
supraorbital n supratrochlear n. posterior ethmoidal n. anterior ethmoidal n.
43
nerve to frontal sinus
V1 - supraorbital and supratrochlear
44
ethmoid sinus nerve
posterior ethmoidal n
45
anterior ethmoidal n
provides: - branches to ethmoidal air cells - septal branches - lateral branch nasal cavity - external nasal branch - dorsum of nose
46
maxillary nerve
V2 - branch of trigeminal enters PPF via pterygopalatine fossa -GSA to nose and sinuses
47
branches of V2
``` infraobribal posterior superior alveolar nasopalatine posterior superior lateral nasal posterior inferior lateral nasal ```
48
majority of innervation to nasal septum
nasopalatine n
49
maxillary sinus nerve
infraorbital -via V2 also to face and lateral nose
50
maxilalry sinus nerve
posterior superior alveolar n | -via V2
51
superior lateral nasal wall nerve
posterior superior lateral nasal n
52
posterior inferior lateral nasal wall nerve
posterior inferior lateral nasal n
53
parasympathetic to paranasal sinuses
preganglionic - salivatory nucleus travel with CN VII - greater petrosal branch - joins deep petrosal nerve - form nerve to pterygoid canal synapse at PPG -postganglionic with V2 > nasal cavities and sinuses
54
sympathetics to paranasal sinuses
preganglionic T1 - 4 postganglionic SCG -fibers with internal carotid n > deep petrosal n with greater petrosal nerve -form nerve to pterygoid canal - synapse at PPG - postganglionic with V2 > nasal cavities and sinuses
55
lymph drainage of nasal cavities
anterior portion - submandibular nodes | posterior portion - retropharyngeal nodes
