The nasal sinus located between the nose and the orbits is the?

Maxillary
Frontal
Ethmoid
Sphenoid

The correct answer is: Ethmoid

The nasal sinus located between the nose and the orbits is the ethmoid sinus. This complex structure comprises a collection of air-filled spaces found within the ethmoid bone, which is situated between the nasal cavity and the orbits (eye sockets). The ethmoid sinuses play a crucial role in respiratory function and the drainage of mucus, while also contributing to the overall shape and function of the nasal cavity. Their location allows them to effectively communicate with both the nasal passages and the orbit, which is essential for proper drainage and function. The maxillary sinus, while also significant, is located in the cheek area, making it distinct from the ethmoid. The frontal sinus is found in the forehead region, and the sphenoid sinus is located deeper within the skull, behind the nasal cavity. Each of these sinuses has its unique anatomical position and function, but the ethmoid sinus specifically occupies the space between the nose and the orbits, thus making it the correct answer in this context.
