Oral And Nasal Flashcards
What does the soft palate do?
Closes the pharyngeal isthmus during deglutination to prevent material from reaching nasopharynx
What vessel of the palatine tonsil can bleed profusely during a tonsilectomy?
Tonsilar v
What is the innervation and blood supply of the palate?
Hard: nasopalatine n and vessels
Soft: Greater and lesser palatine n and vessels
What m of the tongue protrudes it? What happens if there’s a lesion of the hypoglossal n?
Genioglossus (the genie comes out of the bottle!)
Tongue protrudes towards effected/lesioned side
What is palatoglossus innervated by? What is it’s purpose?
Vagus (versus rest of tongue being XII)
Elevates the tongue and closes the faucial isthmus during deglutination
What is the function and innervation of the tensor veli palatini m? Is there a need to examine the whole face?
Tenses soft palate and opens auditory tube
Innervation: mandibular branch of V
Yes because trigeminal innervates many things!
What is the function and innervation of levator veli palatini?
Elevates the soft palate
Innervation is vagus
What muscles might be affected if the uvula is pulled/deviated off-center? Which side is the uvula being pulled to?
Tensor and levator veli palatini
The uvula is pulled towards the normal side
What is the most likely place for epistaxis to occur?
Kiesselbach’s area, in the anterior vestibule of the nose.
What is the innervation and blood supply to the nose?
Innervation: olfactory (SVA), ant ethmoidal n, nasopalatine n
BS: ant and post ehtmoidal a, sphenopalatine a –> pos lateral and septal aa
What sinus forms the floors of the orbit, the lateral walls of the nasal cavity, and the roof of the mouth by the first and second molar? Where does it drain?
Maxillary, hiatus semilunaris
What concha contain vasculature (swell bodies) that’s pertinent to air flow during a cold?
Inferior and middle concha
What often breaks from an external force to the nose? Where do these pieces often displace?
Pterygoid plates, somewhere at the junction between the septal cartilage and vomer and ethmoid bones
Displace posteriorly
What is the purpose of the fat pad in the cheek? What innervates the skin of the cheek?
Provides leverage for sucking
Long buccal n of the mandibular branch of the trigeminal
What does the parotid duct pierce?
Buccinator m
