description of the palate

Answer 1

forms the roof of the oral cavity and the floor of the nasal cavity

Question 2

structure of palate= hard palate

Answer 2

1. anterior 2/3 is palatine process of maxilla bones

2. posterior 1/3 is horizontal plates of the palatine bones

Question 3

hard palate, above it is covered by respiratory mucosa and forms

Answer 3

the floor of the nasal cavities

Question 4

hard palate, below it is covered by a tightly bound layer of

Answer 4

oral mucosa and forms much of the roof of the oral cavity

Question 5

the mucosa of the hard palate in oral cavity possesses numerous transverse palatine folds(palatine rugae) and

Answer 5

and a median longitudinal ridge(palatine raphe)

Question 6

soft palate is

Answer 6

movable by four muscles

Question 7

soft palate is suspended to hard palate by

Answer 7

palatine aponeurosis

Question 8

soft palate has a soft free margin called

Answer 8

uvula

Question 9

soft palate act as a valve

Answer 9

INF= depressed to help close the oropharyngeal isthmus(seal off oral cavity e.g holding water in the mouth while breathing)

S= elevated to separate the nasopharynx from the oropharynx= ( seal off nasal cavity when swallowing)

Question 10

features of palate

Answer 10

1. consists of a bony plate covered above and below by mucosa
2. embedded palatine glands secrete saliva

Question 11

muscles of the palate arises from the

Answer 11

base of the skull and descend to palate

Question 12

tensor veli palatini

Answer 12

1. sup attachment= ( sphenoid fossa of medial pterygoid plate, spine of sphenoid bone, cartilage of pharyngotympanic tube)
2. inferior attach= palatine aponeurosis
3. IN= medial pterygoid nerve which is a branch of mandibular nerve CNV3 via otic ganglion
4. MA= a. tenses soft palate
   b. opens mouth of pharyngotympanic tube during swallowing and yawning

Question 13

levater veli palatini

Answer 13

SA= cartilage of pharyngotympanic tube and petrous part of the temporal bone

IA= palatine aponeurosis

IN= pharyngeal branch of vagus nerve CNX via pharyngeal plexus

MA= elevates soft palate during swallowing and yawning

Question 14

platoglossus

Answer 14

1. SA= palatine aponeurosis
2. IA= side of the tongue
3. IN= pharyngeal branch of vagus nerve CNX via pharyngeal plexus
4. MA= elevates posterior part of the tongue and draws soft palate onto tongue

Question 15

platopharyngeus=muscle of the tongue

Answer 15

1. SA= hard palate and palatine aponeurosis
2. IA= lateral wall of pharynx
3. IN= pharyngeal branch of vagus nerve CNX via pharyngeal plexus
4. MA= tenses soft palate and pulls walls of pharynx superiorly, anteriorly and medially during swallowing

Question 16

musculus uvulae

Answer 16

1. SA= posterior nasal spine and palatine aponeurosis
2. IA= mucosa of uvula
3. IN= pharyngeal branch of vagus nerve
4. MA= shortens uvula and pulls it superiorly

blood supply of of palatine

Answer 17

1. greater palatine artery
2. lesser palatine artery
3. ascending palatine artery
