Turbines and nasal passages

The bone anatomy of the lateral wall of the nasal cavity has three upper, middle and lower turbinates, and the lower three nasal tissues are called upper, middle and lower nasal passages. The upper turbinate and the middle turbinate are part of the inner wall of the ethmoid. The inferior turbinate is a separate bony structure with the lateral side connected to the maxilla. The nasal passages between the turbinate are the openings of some important sinuses. The maxillary sinus is in the maxilla and opens in the middle nasal passage. The lowest point of the sinus is lower than the opening. The frontal sinus is in the frontal scaly and opens in the middle nasal passage. The ethmoid sinus is the most vacuole in the ethmoid sinus. It is divided into three groups through the nasal cavity. The anterior and middle groups open the middle nasal passage, and the posterior group opens in the upper nasal passage. The sphenoid sinus is located in the sphenoid body and opens in the stencil crypt.
