Frontal
mucus, air moisten air
Sphenoid

Ethmoid
Lubrication/mucus, voice resonate
Name for the openings into the nosse
external nares (nostrils)
Internal narses
connect nose & pharynx
What line the vestibules (nasal cavities inside the nostrils)
Coarse hairs: filters large dust particles - 1st line of defense
Is formed by three bones, has a superior, middle&inferior meatus (lined with muucus membranr)
three shelves
What is located in the superior meatus
*internal nose functions, warm&moisturizes air, smell, speech tone
Olfactory receptors

plaryngeal/adenoid tonsils l
Oropharynx is connected to the
mouth (fauces)
Connects with esophagus and larynx
Laryngopharynx
What is supported by cartilage and connects pharynx with trachea
Larynx
Prevents food from entering trachea
epiglottis
attach to vocal cords & laryngeal muscles
arytenoid
connect epioglottis to arytenoid
Corniculate &cuneiform
connects with first tracheal ring
cricoid
tubular passageway for air
-anterior to esophagus
- extands from cricoid cartilage to 5 thoratioc vertebra
trachea
What has cili & goblet cells
Pseudostratified epithelium
Supporting cartilage
stack of C’s with open part face esophagus allowing it to expland into trachea during swallowing
Tracheostomy
incision into trachea creating opening for air to enter
