Here’s a clear textual breakdown of a diagram of the human nose (I can also generate an actual labeled image if you want):
1. External Nose (visible part):
-
Nasal bridge: The upper bony part of the nose.
-
Nostrils (nares): Openings for air entry.
-
Nasal tip: The pointed end of the nose.
-
Ala (plural: alae): The flared sides around the nostrils.
-
Columella: Tissue that separates the two nostrils.
2. Nasal Cavity (internal):
-
Nasal septum: Divides the nasal cavity into right and left sides; made of cartilage and bone.
-
Nasal conchae (turbinates): Three curved bony structures (superior, middle, inferior) that increase surface area for warming and humidifying air.
-
Nasal meatuses: Passages beneath each concha for air flow.
-
Olfactory epithelium: Located at the top of the nasal cavity; responsible for smell.
-
Respiratory epithelium: Lines most of the nasal cavity; contains mucus-secreting cells.
3. Sinuses (connected to nasal cavity):
-
Frontal sinus: In the forehead above the eyes.
-
Maxillary sinus: Cheek area beside the nose.
-
Ethmoid sinus: Between the eyes.
-
Sphenoid sinus: Behind the ethmoid, deeper in the skull.
4. Nasopharynx (back of nasal cavity):
-
Connects nasal cavity to throat.
-
Eustachian tube opening: Connects to the middle ear for pressure equalization.
