Anatomy and innervation of Hard Palate

?
why is the hard palate called a mucoperiosteum
because it adheres to bone
1 of 21
how many bones make the H palate? name them
2 palatine processes of maxillae. 2 palatine bones (the horizontal plate)
2 of 21
describe the epithelium of hard and soft palate
hard: keratinised stratified squamous soft: non keratinised stratified squamous
3 of 21
what is the function of palatine rugae
ensures breaking down of food effiencintly
4 of 21
what is palatine raphe
the fusion of the left. and right structure
5 of 21
what is the cause of theft palate
failure of lateral palatine processes
6 of 21
where do the greater and lesser nerves. and arteries come from
pterygopalatine ganglion
7 of 21
what does the incisive branch of nasapalatine nerve supply
the front half of the hard palate. also the mucosa and gingiva of upper anterior teeth
8 of 21
what does the jugulo-digastric node drain
the palatine tonsil
9 of 21
Where does the posterior part hard palate and the soft palate drain
in the retropharyngeal nodes and deep cervical nodes
10 of 21
where does the anterior part of hard palate drain
submandibular lymph nodes
11 of 21
name the posterior and anterior arch in the mouth
posterior: palatopharyngeal anterior: palatoglossal
12 of 21
from where and. to where does each arch go
posterior arch: from soft palate down into pharynx. anterior: from soft palate and inserts into the side of tongue
13 of 21
what are the 5 muscles of the most palate and what are they innervated by
1. levator veli palitini (CN X) 2. tensor veli palatini (CN V3) 3. musculus uvulae CN X 4. palatoglossusCN X 5. palatopharyngeus CN X
14 of 21
To what does tensor veil palatine attach
sphenoid bone
15 of 21
what does the tensor veli palitini do
turns medially around the pterygoid hamulus and enters the soft palate. then it flattens out within the soft palate and joins with the tendon of the opposite muscle to form the palatine aponeurosis
16 of 21
from where to where does the salpingopharyngeus go
auditory tube to pharynx
17 of 21
rom where to where does the tensor veli palitini go
sphenoid bone to soft palate
18 of 21
rom where to where does the levator veli palatini go
from petrous temporal bone to soft palate
19 of 21
how to test and what would be the results for CN X
ask the patient to say aahh. if the uvula lifts straight up in the midline- nerve are functioning normally. if the. uvula pulls to one side- the nerve on the opposite side is damaged
