dissection - OC Flashcards
what does genioglossis do
wide range of actions
intrinsic muscles
transverse
vertical
inferior longitudinal
superior longitudinal
nerve supply to muscles of the tongue
hypoglossal
apart from palatoglossal - X
action of geniohyoid
raise hyoid
act of mylohyoid
raise hyoid and floor of oral cavity
what does styloglossus do
retract tongue
elevate side of tongue
what does hyoglossis do
depress tongue and sides of tongue
how many parts make up the submandibular gland
2 lobes
one superficial
one deep
where are the lobes of the submandibualr gland
superficual- posterior part of inferior border of mandible
deep- lies between oral mucosa and floor of mouth
where are calculi likey to block the submandibular duct
bend around mylohyoid or
near the exit at the sublingual papillae
what happens if you salivate when duct is blocked
expansion of duct
blue swelling
function of glossopharyngeal in tongue
posterior 1/3of tongue
action of tensor veil palatini
tense the soft palate
action of lavatory veli palatini
elevates the soft palate
innervetaion of LVP and TVP
LVP - vagus
TVP- V3
palatoglossus action and innervation
elevate tongue, depress soft palate
vagus
palatopharyngeus action and innvervation
elevate pharynx
vagus
what is it called when the muscoa is bound tightly to bone
mucoperiosteum
what does the greater palatine nerve supply
muscoa of hard palate
sensory innervation of the maxillary dentition
V2
sensory innveration of the mandibular dentiton
inferior alveolar nerve
v3
sensory innvertatio of palatal gingive
nasopalatine
greater palatine nerve
sensory innervation of lingual gingivae
lingual
sensory innervation of maxillary labila and buccal gingiva
long buccal nerve
infraorbital
