Definition
parietal pleura
Term
inner layer pleura
Definition
Visceral
Term
what is the parietal pleura attached to?
Definition
thoracic walls and the diaphragm
Term
purpose of the pleura cavity
Definition
lubricating seous fluid causes them to adhere closely to one another, holding lungs to the thoracic wall and allowing them to move easily against one another during the movements of breathing
Term
major structures in the nasal cavity
Definition
nasal septum, inferior, middle and superior conchae
Term
flowpath of air over conchae
Definition
inferior, superior then middle

list the paranasal sinuses
Definition
maxillary, frontal, ethmoid, and sphenoid sinus
Term
helpful hint on locating paranasal sinuses
Definition
sinuses are named after the bones in which they are located
Term
purpose of paranasal sinuses
Definition
act as resonance chambers in speecha nd act like the mucosae
Term
what separates nasal cavity from oral cavity?
Definition
hard and soft palate
Term
relative to each other where are the hard and soft palate located?
Definition
anteriorly: hard palate and posteriorly: soft palate
Term
list the 3 types of pharynx
Definition
naso, oro and laryngo
Term
location of nasopharynx

Term
purpose of pharyngeal and tubal tonsils
Definition
pharyngeal: protect respiratory tract
tubal: protect middle ear
Term
location of the orpharynx
Definition
extends from soft palate to epiglottis of the larynx inferiorly
Term
purpose of oropharynx
Definition
common conduit for food and air
Term
protective "attachments" of oropharynx
