There are two nasal bones in the human face.
Understanding the Nasal Bones
The nasal bones are crucial components of the facial skeleton. They are not singular; instead, there are two, symmetrical bones that contribute to the structure and shape of the nose.
Location and Function
- Location: These small, oblong bones are located in the midface, specifically where they form the bridge of the nose.
- Structure: Each nasal bone has two surfaces and four borders.
- Function:
- They join at the midline of the face to create the superior aspect of the nasal bridge.
- Inferiorly, they serve as an anchor point for the upper lateral nasal cartilages.
- They contribute to the protection of the nasal cavity.
Key Features
| Feature | Description |
|---|---|
| Number | Two |
| Shape | Small, oblong, and symmetrical |
| Surfaces | Each bone has two surfaces |
| Borders | Each bone has four borders |
| Location | Midface, forming the bridge of the nose |
| Articulation | Connect to each other, and upper lateral nasal cartilages |
Clinical Significance
- Fractures of the nasal bones are common facial injuries.
- The nasal bones play a role in cosmetic aspects of the nose.
The nasal bones are important for both structural integrity and the cosmetic appearance of the nose, and their paired nature is fundamental to understanding their anatomy.
