Nasal Anatomy And Physiology

Anatomy of the nose.

Nasal passage anatomy. The ridges are named for their position. The nasal cavity refers to the interior of the nose. The nasal cavity extends from the external opening the nostrils.

The flow of air from outside of the body to the lungs begins with the nose which is divided into the left and right nasal passages. In bones behind your nose are your sphenoid sinuses. As you breathe in air through your nose and.

The nasal cavity is surrounded by a. Theyre lined with soft pink tissue called mucosa. Openings into the nasal cavity.

The exhaled air travels in the reverse path and leaves the body through the nasal cavity. The external nose consists of paired nasal bones and upper and lower lateral cartilages. The lateral nasal wall consists of inferior and middle turbinates and occasionally a superior or supreme turbinate bone.

Projecting out of the lateral walls of the nasal cavity are curved shelves of bone. The sinuses are part of your nose and respiratory system. The turbinates consist of three ridges of thin shell like bone known as the nasal conchae.

The nasal passages are lined with a membrane composed primarily of one layer of flat closely packed cells called epithelial cells. Superior middle and inferior meatus. The nasal cavity divisions.

Just beneath each concha is a passage known as the meatus named for the adjacent turbinate. Anatomy of the nasal passages. Role as a passage for inhaled air.

Beyond the nasal valve the nasal passages are lined mostly by membranes more like the lining of the lungs called respiratory epithelium which is thin and rich in blood vessels. Internally the nasal septum divides the nasal cavity into a right and left side. Anatomy of the nasal cavity.

This region is divided into a labyrinth of slit like passages by multiple bony proturbances that fill the nose and act as shelves. They connect to your nasal passages in a complex network of air flow and drainage passages. The superior the middle and the inferior turbinates.

One of the functions of the nose is to drain a variety. The nasal cavity is the most superior part of the respiratory tract. Normally the sinuses are empty except for a thin layer of mucus.

During inhalation air enters through the nostrils and passes via the nasal cavity into the pharynx and larynx the next sections in the respiratory tract to eventually reach the lungs.
