The picture is blurry but I need help with the bone names around the nasal cavity! I first thought it was

1. Lacrimal bone 

2. Ethmoid bone 

3. Nasal bone

 4. ?? 

5. Vomer 

But I am not 100% sure. I need some clarification!

    There are 12 cranial bones in total that contribute to the nasal cavity structure, which include the paired nasal, maxilla, palatine and lacrimal bones, as well as the unpaired ethmoid, sphenoid, frontal and vomer bones.. Ethmoid sinuses: The ethmoid sinuses are located in the ethmoid bone, which separates the nasal cavity from the brain. These sinuses are not single sacs but a collection of six to 12 small air cells that open independently into the nasal cavity. They are divided into front, middle, and rear groups.
