Study Notes
Inferior Nasal Conchae
- Create spaces (meati) within the nasal cavity.
- Spaces beneath the superior, middle, and inferior nasal conchae are called nasal meati.
- Increased surface area due to conchae is crucial.
- Without conchae, nasal cavity would be simple passageways.
- Increased surface area allows for more contact with the mucus membrane.
Mucus Membrane Function
- Trapping foreign particles (e.g., fruit flies).
- Transporting particles to digestive tract (swallowed).
- Preventing foreign particles from lungs (for safety).
- Humidifying and warming incoming air to protect throat/pharynx.
Importance of Humidity and Temperature in Air
- Pharynx is sensitive to cold, dry air.
- Cold air can cause throat irritation, especially during strenuous exercise.
- The mucus membrane in nasal cavity warms and moistens incoming air.
Surface Area and Nasal Conchae
- Increased surface area due to conchae allows for better trapping of particles and warming/moistening of air.
Olfactory Receptors
- Olfactory receptors are located within the nasal meati.
- Olfactory receptors detect scents.
- These receptors are connected to cranial nerve I (olfactory nerve).
- They transmit scent information to the brain.
Air Flow
- Nasal conchae create a pathway that the air gets swirled and circulated.
