Final answer:

The bones that do not house a paranasal sinus are the nasal, lacrimal, palatine, inferior nasal conchae, mandible, and vomer. These bones have different roles in the skull's anatomy, such as forming parts of the nasal septum and the orbits.

Step-by-step explanation:

The bones that do not house a paranasal sinus are the nasal, lacrimal, palatine, inferior nasal conchae, mandible, and vomer. The paranasal sinuses are air-filled spaces found within specific bones around the nasal cavity. The sinuses include the frontal sinus in the frontal bone, the maxillary sinuses in the maxilla bones, the sphenoid sinus within the sphenoid bone, and the ethmoid air cells in the ethmoid bone. The bones that do not contain paranasal sinuses do not participate in this sinus structure and have other roles within the skull anatomy, like forming the nasal septum, or the orbits, which house the eyes and associated muscles.
The nasal conchae, which include the large independent inferior nasal concha and parts of the ethmoid bone, are bony projections that do not contain sinuses but increase the surface area of the nasal cavity. The nasal septum is composed of the perpendicular plate of the ethmoid bone, the vomer bone, and the septal cartilage. The facial bones of the skull, such as the nasal and palatine bones, contribute to the nasal septum and the structure of the face but do not contain paranasal sinuses.
