Nasal bone
The Nasal bone is one of the two small oblong bones varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face and form, by their junction, "the bridge" of the nose. Each has two surfaces and four borders.
Structure[edit | edit source]
The nasal bone is an oblong bone which varies in size and form in different individuals. It is placed side by side at the middle and upper part of the face, and by their junction, forms "the bridge" of the nose. Each bone has two surfaces and four borders.
Surfaces[edit | edit source]
The outer surface is concave, and forms part of the nasal dorsum and the nasal cavity. The inner surface is concave and forms part of the nasal cavity.
Borders[edit | edit source]
The superior border, thick and uneven, articulates with the nasal notch of the frontal bone, and is marked by a groove for the passage of the nasal nerve. The inferior border is thin, and corresponds with the line of junction of the septum of the nose with the vomer. The lateral border is serrated for articulation with its fellow of the opposite side.
Clinical significance[edit | edit source]
Injury to the nasal bone can cause nasal fracture, which may lead to nasal deformity if not treated properly. Nasal bone fractures are the most common types of facial fractures, but they are relatively easy to treat due to the bone's accessibility.
Other animals[edit | edit source]
In many animals, the nasal bones contain the nasal cavity, which houses the olfactory bulbs.
