Final answer:

The bones with sinuses in the nasal cavity are the frontal, maxillary, ethmoid, and sphenoid bones.

Step-by-step explanation:

The four bones of the nasal cavity that have sinuses include the frontal, maxillary, ethmoid, and sphenoid bones. The paranasal sinuses in these bones are air-filled spaces that contribute to the structure of the nasal cavity. Specifically, the frontal sinus is found in the frontal bone above the eyebrows, while the maxillary sinuses are located within the maxillary bones. The sphenoid sinus is located in the body of the sphenoid bone, and the ethmoid air cells are situated within the ethmoid bone between the orbit and the upper nasal cavity. These sinuses play various roles including the lightening of the skull bones, aiding in sound resonance, and providing a level of immune defense.
