Study Notes
The Nose
- The nose is the part of the respiratory tract above the hard palate
- Contains the organ of smell (olfaction)
- Includes both the external nose and the nasal cavity
- Functions include smelling, breathing, filtering dust, humidifying air, and draining secretions.
Pterygopalatine Fossa
- Major distribution center for maxillary nerve branches and pterygopalatine part of the maxillary artery
- Located between the infratemporal fossa, nasal cavity, orbit, and other structures
- Contains the maxillary nerve (CN V₂), the parasympathetic pterygopalatine ganglion, the third part of the maxillary artery, and accompanying veins, plus fatty tissue.
External Nose
- Visible portion projecting from the face
- Primarily composed of cartilage.
- Shape varies greatly due to cartilage differences
- Dorsum extends from the nose root to tip.
- Nares (nostrils) are two pear-shaped openings at the inferior surface.
- Alae (wings) border the nares laterally.
- The superior bony part of the nose (including the root) has thin skin.
- Thicker skin covers the cartilages and contains sebaceous glands
- Vibrissae (stiff hairs) filter dust particles entering the nasal cavity.
- Junction of the skin and mucosa is beyond the hair-bearing zone.
Nasal Skeleton
- Bony components include the nasal bones, frontal processes of the maxillae, nasal part of the frontal bone and its nasal spine, along with parts of the nasal septum.
- Cartilaginous components include two lateral cartilages, two alar cartilages, and one septal cartilage
- The alar cartilages are flexible and can change the size of the nares.
Nasal Septum
- Divides the nasal cavity into two halves.
- Includes the perpendicular plate of the ethmoid, the vomer, and septal cartilage.
Nasal Cavities
- The term nasal cavity refers to the whole or a single side
- Lined by mucosa, except for the nasal vestibule.
- Mucosa is firmly bound to bone and cartilage, connecting to other structures
- Superior one-third (olfactory area) contains the organ of smell
- Inferior two-thirds (respiratory area): warms and moistens air before it enters the lungs.
