Nasal cavity + sinuses Flashcards
what is the roof and floor of the int nose
roof- cribiform plate
floor- palantine process of maxilla + horizontal plate of palantine
Lat wall of the int nose from ant to post
- frontal process of max
- med wall of ethmoidal labrinth + conchea
- Inf nasal conche
- Perpendicular bone of palantine
- Medial pterygoid plate
what are the 3 conchea in the nose
- sup
- middle
- inf
what are the 2 sinuses inside the nose
frontal sinus
sphenoid sinus
What type of epithelium is located right across sup nasal septum
covered by olphactory epithelium (some bipolar CN1 branches)
where does the sphenoid sinus and post ethmoidal air cells open to
superior nasal meatus
Where do the other sinus (other than sphenoid and post ethmoidal) open up to
middle nasal meatus (thru infundibulum + semilunar hiatus)
where does lacrimal fluid drain
thru nasolacrimal duct into inf nasal meatus
What portion of the nose is inv by CNV1 (opthalmic)
Ant, sup part of the wall and septum
Int nasal
What portion of the nose is inv by CNv2 (maxillary) + branches
Post inf part of septum and wall
Post lateral sup + inf, nasopalantine n (sphenopalantine + incicive)
what inn the pterygopalantine ganglion
greater petrosal n
blood branches located inside the nose
- ant+post ethmoidal a
- sphenopalantine
- Incicive
- Greater palantine
- Septal a
What are does the artieries in the nose create
Kisselback area arterial plexus
what is rhinitis
inflamation of nasal mucosa, blockage of air will decrease the air exchange
What is sinitis associated w
sinitus is frequently accompanied by a sensation of toothache in molar teeth since sup alveolar nerves supply both the maxillary teeth and mucosa of maxillary sinus
