The ethmoidal process of the inferior concha is just posterior to the lacrimal process.
What is the main source of arterial blood to the nose?
The nose has a rich vascular supply, with substantial contributions from the internal carotid artery (ICA) and the external carotid artery (ECA). The ECA system supplies blood to the nose via the facial and internal maxillary arteries. The superior labial artery is one of the terminal branches of the facial artery.
Where are the inferior and middle nasal concha located?
While the superior and middle nasal conchae form part of the perpendicular plate of the ethmoid bone, the inferior nasal concha is a bony structure by itself. It sits on the vertical bony plate known as the nasal septum, separating the nasal cavity into two bilateral and symmetrical anatomical caves.
What are 3 functions of the nasal cavity?
The nasal cavity functions to humidify, warm, filter, and act as a conduit for inspired air, as well as protect the respiratory tract through the use of the mucociliary system. The nasal cavity also houses the receptors responsible for olfaction.
Where is the nasal concha bone located?
The conchae are located laterally in the nasal cavities, curling medially and downward into the nasal airway. Each pair is composed of one concha in either side of the nasal cavity, divided by the septum.
