Nasal Cavities and Conchae
Divided medially by nasal septum -hyaline
PSCC epithelium (roof lined with olfactory epithelium)
Conchae - vascular bony shelves
Filter warm and incoming air
Nasopharynx
PSCC
Pharyngeal tonsil- adenoid (enlarged lymphatic tissue at back of nose and throat)
Paranasal sinuses
Open into nasal cavity to lighten the skull
Assist to moisten and warm air
Contain mucous cells which drain in nasal cavity
Frontal, ethmoidal, maxillary, sphenoidal
Larynx
Connects pharynx to trachea
PSCC (vocal cords and epiglottis are SSNK)
Phonation
Guard against entry of foreign bodies
Vocal cords
Glottis - space between
Laryngeal muscles control length and size of muscles by moving arytenoid cartillages
Sound produced by vibration as air exhaled
