is a small, thin, plow-shaped, midline bone
that occupies and divides the nasal cavity. It articulates inferiorly on the midline with the maxillae and the palatines, superiorly with the sphenoid via its wings, and anterosuperiorly with the ethmoid.

For this reason, how many lacrimal bones are there?
Spanning between the middle of each eye socket, each lacrimal is thin and scalelike and serves as support for the eye. The pair of lacrimal bones are two of the fourteen facial bones.
So anyway, is the lacrimal bone paired? The paired bones are the maxilla, palatine, zygomatic, nasal, lacrimal, and inferior nasal conchae bones. The unpaired bones are the vomer and mandible bones.
Forbye, what bone is the vomer part of?
The vomer is part of the nasal septum which follows the midline of the viscerocranium and creates the division between the two symmetrical sides of the nasal cavity. The vomer articulates with the palatine, maxilla, ethmoid and sphenoid bones.
What is nasal bone?
Each human has two nasal bones located in the upper-middle area of the face, between the maxillary (upper jaw) bones' frontal processes. These sit midline to each other to form the bridge of the nose. Nasal bones are normally small and oblong, but can differ in size and shape in different people.
