Deep Face Flashcards
Glossopharyngeal nerve (CN IX)
supplies sympathetic innervation to deep face
parotid gland is a
(serus) salivary gland
the parotid gland dumps into

the parotid duct runs _____ and dumps into _____
anterior; the cheek
the facial nerve runs in between
the superficial lobe and the deep lobe of the parotid gland
the submandibular and the sublingual glands are
seromucous glands
the submandibular and the sublingual glands are innervated by
the facial nerve
the sublingual gland is located
under the tongue
the submandibular gland is ______ than the sublingual and is located
longer; under the frenulum of the tongue
Muscles of mastication
temporal, masseter, medial and lateral pterygoid
temporal muscle
main muscle of mastication
masseter location
cheek area
medial pterygoid
shuts mouth, pulls jaw forward
lateral pterygoid
unlocks jaw, pulls jaw up
muscles of mastication innervated by
trigeminal
medial pterygoid location
deep to masseter
maxillary branch of external carotid artery
supplies deep face
extrinsic tongue muscles
mylohyoid, geniohyoid
genioglossus
main muscle of tongue
longitudinal tongue muscles
run anterior to posterior towards the surface of the tongue
foramen cecum
hole from descent of thyroid gland
thyroid gland descends from
the posterior aspect of the tongue
concha of nasal cavity
sup, middle, and inf; add surface area and cause turbulence so the air is warm and moist
maxillary sinus can get infections bc
fluid doesn’t drain from it as well
sphenoid sinus
fluid drains at bottom
inferior aveolar artery
goes to lower teeth
superior aveolar artery
goes to upper teeth
what nerves are located under the tongue?
lingual and hypoglossal
what artery is located under the tongue? and what does it give off?
lingual; deep lingual and sublingual
Genioglossus action
protrudes tongue and depresses center
Genioglossus origin and insertion
o: superior mental tubercle
i: body of the hyoid and the tongue
hyoglossus action
depression of the lateral surface of the tongue
hyoglossus origin and insertion
o: greater horn and body of the hyoid
i: lateral surface of the tongue
styloglossus action
elevates and retracts tongue
styloglossus origin and insertion
o: styloid process
i: lateral surface of the tongue
palatoglossus action
depress palate and elevate posterior tongue
palatoglossus origin and insertion
o; inferior palatal aponeurosis
i: lateral surface of the tongue
palatoglossus innerv
vegas
extrinsic muscles of the tongue are innervated by the
hypoglossal (except the palatoglossus)
right frontal sinus is located
posterior to the superciliary arches and nose
the maxillary sinus is located
laterally
the opening for the maxillary sinus is under the
middle meatus
frontal paranasal sinus drainage
through ethmoidal infundibulum into semilunar hiatus
ethmoidal paranasal sinus drainage
ant-middle meatus, midle-middle meatus, post-superior meatus
middle meatus located
under middle cochea
sphenoidal paranasal sinus
in body of sphenoid drains to spenoethmoidal recess
maxillary paranasal sinus drains
through maxillary ostium to middle meatus
