Q

What is the small particle filter of the respiratory system?

A

Serous products of the seromucus glands

lysozyme, interferons, cytokines, air humidity

20
Q

What is located in the lamina propria of the respiratory region of the nasal cavity?

A
  1. Seromucus glands

2. Cavernous plexus (large venules)

21
Q

What are the functions of the cavernous plexus in the lamina propria?

A
  1. Warm air
  2. Humidify air
  3. Provide defense (inflammation)
22
Q

As blood volume increases, venules enlarge and lamina propria increases in size as leumen size decreases. What does this cause?

A

Stuffy nose

23
Q

As blood volume increases, oxygen increases and stimulates seromucus gland secretion. What does this cause?

A

Runny nose

24
Q

What supports the respiratory portion of the nasal cavity?

A

Hyaline cartilage and bone

25
Q

Where are paranasal sinuses located?

A
  1. Ethmoid
  2. Sphenoid
  3. Frontal bone
  4. Maxilla
26
Q

How do the paranasal sinuses connect to the nasal cavity?

A

Through sinal ostia

27
Q

What is the epithelium lining the paranasal sinuses?

A

Respiratory epithelium

28
Q

What does the lamina propria of the paranasal sinuses contain?

A
  1. Seromucus glands

2. Blood vessels

29
Q

What can happen if there are small ostia in the paranasal sinuses and the lamina propria swells?

A

Ostia can become blocked and may result in a sinus infection

30
Q

What are the three subdivisions of the pharynx?

A
  1. Nasopharynx (superior)
  2. Oropharynx (middle)
  3. Laryngopharynx (inferior)
31
Q

What is the surface epithelium of the nasopharynx?

A

Respiratory epithelium with mucociliary clearance

32
Q

What is the surface epithelium of the oropharynx and laryngopharynx?

A

Stratified squamous epithelium

33
Q

What is the lamina propria of the pharynx composed of?

A

Loose connective tissue

34
Q

Where are the pharyngeal tonsils located?

A

Nasopharynx

35
Q

Where are the palatine and lingual tonsils located?

A

Oropharynx

36
Q

Which subdivision of the pharynx does not contain tonsils?

A

Laryngopharynx

37
Q

Are there tonsils located in the muscularis mucosa of the pharynx?

A

No

38
Q

Where is pharyngobasilar fascia located in the pharynx?

A

Submucosa

39
Q

What is the name for the collagen in the periosteum of the basilar portion of the occiput that blends into the wall of the pharynx?

A

Pharyngobasilar Fascia

40
Q

What is the function of the pharyngobasilar fascia?

A

Added support

41
Q

What is unusual about the muscularis externa of the pharynx?

A
