The nasal bone is a small, paired bone that forms the bridge of the nose, contributing significantly to the facial skeleton's shape and structure. It several bones, integrating the nasal framework with the rest of the skull. The bones it articulates with include: The ethmoid bone; The opposite nasal bone; The maxilla; The frontal bone.

The nasal bone is a small, bone that varies in size and shape among individuals, forming the bony bridge of the nose. It provides attachment points for the cartilaginous structures of the nose.
On the inferior surface of the nasal bone lies the ethmoidal groove, through which the anterior ethmoidal artery and nerve pass. These structures supply blood and sensory innervation to the nasal mucosa.
The external surface of the nasal bone features the nasal foramen, a small opening located near the center. This foramen allows passage for a small vein from the nasal cavity to the facial vein, contributing to venous drainage of the nasal region.
