Anatomy of Nasal Cavity – Borders, Para Nasal Sinuses, Linings & Mucosa, Vasculature, and Nerve Supply

In Anatomy of Nasal Cavity – By the Structure, The nasal cavity is divided into two halves by a septum and from behind passes through the choana into the upper part of the pharyngeal cavity – the nasopharynx. There are three walls of the nasal cavity: The upper one is formed partially by the frontal bone, the ethmoid plate of the ethmoid bone, the sphenoid bone. The nasal cavity extends from the external opening, the nostrils, to the pharynx (the upper section of the throat), where it joins the remainder of the respiratory system. It is separated down the middle by the nasal septum, a piece of cartilage that shapes and separates the nostrils.
