Paranasal Sinuses Flashcards
What are the bony structures within the nose? Meatuses(Spaces)?
Bone=Superior, middle, and inferior nasal concha.
Spaces=
- Above superior concha=Sphenoethmoidal recess
- Below superior=Superior meatus
- Below middle=Middle meatus
- Below inferior=Inferior meatus.
What is the sensation and parasympathetic innervations of the nasal cavity?
Sensation: V1 and V2
Para=VII via greater petrosal
What are the lymphatics of nasal cavity?
Submandibular or retropharyngeal nodes.
What are nasal cavity gateways?
- Cribiform plate
- Sphenopalatine foramen
- Incisive canal
- Small lateral wall foramina
- Nares
What is the drainage, innervation, arterial supply, and lymphatics of frontal sinus?
D: Middle meatus
I: Supraorbital and supratrochlear of V1
A: Anterior ethmoid, Supraorbital and supratrochelar
L: Submandibular nodes
What is the drainage (anterior,posterior, middle), innervation, arterial supply, and lymphatics of ethmoid sinuses?
D: Posterior=superior meatus
Anterior/middle: middle meatus
I: Anterior/posterior ethmoid of V1
A: Anterior/post ethmoid a, Posterior lateral branches from sphenopalatine
L: Submandibular and retropharyngeal nodes.
What is the drainage, innervation, arterial supply, and lymphatics of sphenoid sinus?
D: Sphenoethmoid recess
I: Posterior ethmoid (V1)
A: Posterior ethmoid artery, Pharyngeal a
L: Retropharyngeal nodes
What are the superior, inferior, medial, lateral, and posterior relations of the maxilary sinus?
- Superior=Orbit, infraorbital n,a,v
- Inferior=Roots of molars and premolars
- Medial=Nasal cavity
- Lateral and anterior=Cheek
- Posterior=Infratemporal fossa, pterygopalatine fossa
What is the drainage, innervations, arteries, and lymphs of maxillary sinus?
D: Middle nasal meatus
I: AsA, MSA, PSA
A: Infraorbital, ASA, MSA, PSA
L: Submandibular nodes
What is sinusitis?
Sinus cavities inflamed.
What is the floor of the oral cavity?
- Mylohyoid
- Geniohyoid
- Tongue
What passes through the gateway into the floor of the oral cavity? Also called?
AKA 2nd pharyngeal aperture.
- Stylopharyngeus, hyoglossus, styloglossus m.
- Stylohyoid ligament
- Tonsillar a
- Lingual, glossopharyngeal and hypoglossal nn.
- Lymphatics
- Submandibular gland
What are the papillae of the tongue, locations, taste, keratinized, vascular?
- Filiform: Most numerous, no taste, keratinized (only one, avascular(Only one)
- Fugiform: Margins of tongue, taste, non K, has V
- Vallate or Circumvallate: Large line in V shape, taste, V, no K.
- Foliate: Sides of tongue, no Taste, no K, has V
what are the Extrinsic muscles of the tongue and their innervation?
- Genioglossus CN XII
- Hyoglossus CN XII
- Palatoglossus CNX
- Styloglossus CNXII
What is the Action and innervation of the Superior longitudinal tongue muscle?
A: Shortens and curls tongue up.
I: CN XII
