The nasal bones are small paired oblong upper central facial bones placed side by side between the frontal processes of the maxilla, jointly forming the nasal ridge.
Gross anatomy
The nasal bone has two surfaces:
external surface to which the procerus and nasalis muscles attach
internal, which is transversely concave, with a groove, the ethmoid sulcus, for the anterior ethmoidal nerve
The four borders of the roughly quadrangular nasal bone are:
superior: joins the frontal bone at the frontonasal suture
inferior: free edge, continues as the lateral nasal cartilage
lateral: articulates with the frontal process of the maxilla at the nasomaxillary suture
medial: with a suture between it and its paired fellow at the internasal suture

musculotendinous
Ossification
The nasal bones ossify from a single centre which appears early in the third month within the cartilaginous nasal capsule, which can be assessed during the 12th-week prenatal scan for nasal bone appearance. Its absence is associated with Down syndrome.
