Answer 33

manbular branch of CN V into mandible through mandible fomramen, exists mental foramen as mental nerve supplies lower dentition, lower lip and chin

Question 34

lingual nerver

Answer 34

innervates floor or mouth and tongue not encased in bone any procedures of the floor of mouth the lingual nerve will be anaesthetised branch of V3

Answer 41

palatoglossis | palatopharyngeus

Question 42

direction of tensor veil palatini

Answer 42

down, then hooks around pteryoi hamulus so fibres horizontal

Question 43

what innervates soft palate muscles

Answer 43

vagus | except TVP branch of V3

Question 44

what does the eustation tube do

Answer 44

connects middle ear with back of pharynx | allows drainage of muses secretion to back of pharyxn

Question 45

how is LVP and eustation tube linked

Answer 45

attach around opening of eusattio tube LVP can pull on tube when swallowing LVP opens tube allowing pressure to equalise

Question 46

what happens if a child is born with cleft palate

Answer 46

weak actin of TVP and LVP on auditory attachment (palatal attachment insecure) auditory tube does not open efficiently middle ear doesn't drain (ear infections), conductive hearing loss
