Study Notes
Functions of the Nose
- The primary function of the nose is to warm, humidify, and filter the air we breathe
External Nose Supply
- The external nose is supplied by the trigeminal nerve
Nasal Chamber Division
- The nasal septum divides the nasal chamber into two nasal cavities
Kiesselbach Plexus
- The Kiesselbach plexus in the nose is formed by the convergence of the sphenopalatine artery and the greater palatine artery
Paranasal Sinuses Function
- The function of paranasal sinuses is to produce mucus, regulate air pressure, and add resonance to the voice
Olfactory Epithelium Location
- The olfactory epithelium is located in the roof of the nasal cavity and in the superior concha
Olfactory Nerve Exit
- The olfactory nerves exit through the cribriform plate of the ethmoid bone
Sense of Smell
- The final portion responsible for the sense of smell is the olfactory bulb
Nasal Conchae (Turbinates) Function
- The main function of the nasal conchae (turbinates) is to warm, humidify, and filter the air we breathe
