Both the superior and middle nasal conchae project from parts of the ethmoidal labyrinth part of the ethmoid bone 15 while the inferior nasal concha is an individual bony structure 16.

The facial bones have many functions as each individual bone supports different areas of the face. Firstly the facial bones protect the soft tissues that lie underneath such as the mucous membranes and sensory cells of the nasal cavity the oral cavity the eyes and if the ethmoid is included the pituitary gland of the brain. The function of the paranasal sinuses is a topic of much debate.
Various roles have been suggested. Lightening the weight of the head. Supporting immune defence of the nasal cavity.
Increasing resonance of the voice. The paranasal sinuses are formed during development by the nasal cavity eroding into the surrounding bones. All the sinuses therefore drain.
Each nasal cavity has a lateral wall medial wall roof and floor. The cribriform plate of the ethmoid bone forms the roof of the nasal cavity the ethmoid bone is the part of the cranial base where the fibers of the olfactory nerve pass through which borders above with the nasal bone and the body of. The paired nasal bones form the bridge of the nose and with the frontal process of the maxilla laterally and the nasal process of the frontal bone superiorly.
The inner surface is grooved by the passage of the nasociliary nerve. The nasal cavity functions to allow air to enter the respiratory system upon respiration. Structures within the cavity regulate the flow of air and particles it contains.
The olfactory region of the nasal cavity regulates the sense of smell. The ethmoid bone also ethmoidal bone ethmoid latin. Os ethmoidale is an unpaired bone of the skull that contributes to the medial wall of the orbit the nasal cavity and the nasal septum.
The ethmoid bone includes the cribriform plate with openings that transmit the olfactory nerves CN I and it also houses paranasal sinuses called the ethmoidal air cells.
