What bony structures make up the hard palate

Palatine process of maxillae -anterior 2/3 of hard palate
Horizontal Plates of palatine- posterior 1/3 of hard palate

3

What covers the hard palate

mucous membrane and includes the palatine glands

4

What is the soft palate

fibromuscular element covered by mucous membrane and palatine glands

5

What structure is found at the posterior termination of the soft palate

The Uvula

6

What does the soft palate doe during swallowing

the soft palate elevates, closing the oral pharynx from the nasopharynx

7

Tensor Veli Palatini
Musculus Uvulae
Palatoglossus
Palatopharyngeus

8

What is the origin of the levator veli palatini

temporal bone and Eustachian tube cartilage

9

What is the action of the Levator Veli Palatini

elevate and retract palate

10

What is the origin of the Tensor Veli Palatini

sphenoid bone and Eustachian tube cartilage

11

What is the action of tensor veli palatini

tightens and flattens the palate

12
