Hyoid to soft palate
What are the boundaries of the nasopharynx?
Soft palate/velum to base of the skull
What are 4 major structures of the pharyngeal cavity?
1) Eustachian tube
2) pharyngeal recess

4) salingophraryngeal fold
The pharyngeal cavity is bounded posteriorly by the ________ ________
Cervical vertebrae
What is the function of the pharyngeal cavity?
Changes shape/size during speech
What parts of the pharyngeal cavity constricts for high vowel and for low vowels?
High vowels = upper levels
Low vowels = lower levels
What is the torus tubarius?
Ring of cartilage that surrounds the opening to the Eustachian tube
Where is the opening of the Eustachian tube?
At the torus tubarius
Where does the Eustachian tube run to and from?
From the nasopharynx to the middle ear cavity
What is another name of the pharyngeal recess?
Fossa of rosenmuller
What is the pharyngeal recess?
Deep recess/grove behind the torus tubarius
What is the salpingopharyngeal fold?
Fold of tissue that extends inferiorly belong the torus tubarius
The torus tubarius is continuous with the _____________ ____
Salpingopharyngeal fold
Behind the torus tubarius is the _________ _____
Pharyngeal recess
What are the 5 main structures/structure pairs of the oral cavity?
1) hard palate
2) soft palate
3) anterior faucial pillar and palatoglossus
4) posterior faucial pillar and pallatopharyngus
5) faucial isthmus and palatine tonsils
What are the two structures on the hard palate?
1) rugae
2) median raphe
What are the two structures on the soft palate
1) velum
2) uvula
What is the function of the oral cavity?
Changes considerably during speech and is very important for it
What is the structure that starts at the uvula/velum and runs anteriorly and inferiorly to the tongue?
Anterior faucial pillar
What is the structure that starts at the soft palate and rinds down to the pharynx?
Posterior faucial pillar
Which muscle runs within the anterior faucial pillar?
Palatoglossis
Which muscle runes within the posterior faucial pillar?
Palatopharyngus
What is the space between the faucial pillars called?
Faucial isthmus
Where are the palatine tonsils located?
Faucial isthmus
What are the 4 major structures of the nasal cavity?
1) choanae
2) chonchae/turbinates (and their meatuses)
3) midline nasal septum

What is the choanae?
The entrance to the pharynx from the nasal cavity
What are the three nasal conchae?
1) superior
2) middle
3) inferior
What is mucosa?
Mucous membrane that covers structures in the nasal cavities
What is the function of the nasal cavities?
Transmits energy during nasal speech sounds
What are the 4 paranasal sinuses?
1) maxillary sinus
2) sphenoidal sinus
3) ethmoidal sinus
4) frontal sinus
What are the 2 functions of the paranasal sinuses?
1) communicate with nasal sinuses
2) can influence speech sounds through resonance
What is the largest paranasal sinus?
Maxillary sinus
What is the buccal cavity?
The small space between lips/cheeks and gums/teeth
