Answer 1

palatine process of maxilla and horizontal process of palatine bones

Question 2

what is the function of the palatine rugae

Answer 2

help with movement of food

Question 3

where is the incisive papilla

Answer 3

anterior to rugae overlying the incisive foramen

Question 4

what passes through the incisive foramen

Answer 4

the nasopalatine nerve and the greater palatine atery

Question 5

what is the function of the soft palate

Answer 5

close the oropharyngeal isthmus or separate the oro and nasopharynx

Question 6

what runs down the middle of the hard palate bone

Answer 6

intermaxillary suture

Question 7

what emerges from the greater palatine foramen

Answer 7

greater palatine nerve

Question 8

what emerge from the lesser palatine foramen

Answer 8

lesser palatine nerves

Question 9

what is the soft palate strengthened by

Answer 9

palatine aponeurosis

Question 10

what is the palatine aponeurosis attached to

Answer 10

posterior edge of hard palate and pterygoid hamulus on either side

Question 11

what runs in the midline of the hard palate and can be felt by the tongue

Answer 11

palatine raphe

Question 12

what is the soft and hard palate joined by

Answer 12

palatoglossal and palatopharyngeal arches

Question 13

where do the palatine tonsils sit

Answer 13

in the tonsillar fossa between 2 arches

Question 14

what are the muscles of the soft palate

Answer 14

levator veli palatini, tensor veli palatini, palatopharyngeus, palatoglossus, musculus uvulae

Question 15

what does the levator veli palatini attach to

Answer 15

pharyngotympanic tube and temporal bone

Question 16

what does the levator veli palatini do

Answer 16

lifts palate up

Question 17

what does the tensor veli palatini attach to

Answer 17

scaphoid fossa, spine of sphenoid and pharyngotympanic tube, aponeurosis

Question 18

what does the tensor veli palatini do

Answer 18

tenses soft plate and supports levator
opens auditory tube during swallowing to facilitate pressure exchange

Question 19

where does the palatopharyngeus attach to

Answer 19

hard palate, palatine aponeurosis and lateral wall of pharynx

Question 20

what does the palatoglossus do

Answer 20

draws soft palate down to tongue

Question 21

where does the musculus uvula attach to

Answer 21

posterior nasal spine and palatine aponeurosis and uvula

Question 22

what does the elevation of the soft palate mean for breathing

Answer 22

causes contact with posterior pharynx wall so air passes through the mouth

Question 23

what does the dropping of the palate mean for breathing

Answer 23

pulls isthmus of fauces to the back of the cavity so air passes through nose

Question 24

what is the motor control to the tensor veli palatini

Answer 24

mandibular nerve (CNV3)

Question 25

what is the motor control to all of the palatine muscles except tensor veli palatini

Answer 25

vagus nerve

Question 26

what arteries supplies the palate

Answer 26

greater and lesser palatine arteries (from maxillary artery from ECA)

Question 27

what is the journey of the greater palatine artery

Answer 27

goes through greater palatine foramen and into the incisive fossa and joins sphenopalatine artery

Question 28

what is the venous drainage of the palate

Answer 28

pterygoid venous plexus

Question 29

what supplies the general sensation to the palate

Answer 29

maxillary nerve - lesser and greater palatine nerves (CNV2)

Question 30

what nerve supplies the upper anterior gingiva and mucosa

Answer 30

nasopalatine nerves

Question 31

what palatine muscles form arches

Answer 31

palatoglossus and palatopharyngeus

Question 32

what arch is the posterior boundary of the oral cavity (more anterior)

Answer 32

palatoglossal

Question 33

what is the fauces

Answer 33

the space between the oral cavity and pharynx

Question 34

where is the tonsillar fossa

Answer 34

between the 2 arches

Question 35

what is the uvula

Answer 35

soft tissue projection in oral cavity

Question 36

what does the uvula do

Answer 36

create a seal when swallowing to prevent food/liquids entering the nasopharynx
