Nasal bone
Nasal bone
The Nasal bone (pronunciation: /ˈneɪzəl boʊn/) 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.
Etymology
The term "Nasal bone" is derived from the Latin word "nasus" meaning nose, and the Old English word "bān" meaning bone.
Structure
Each Nasal bone articulates with four bones: two of the cranium, the frontal bone and ethmoid bone, and two of the face, the opposite nasal bone, and the maxilla.
Clinical significance
The nasal bone is often subject to fractures due to its position on the face, and the relatively thin covering of skin and soft tissue. It is often fractured in injuries to the face, particularly facial fractures.
Related terms
