Nose Nose, the prominent structure between the eyes that serves as the entrance to the respiratory tract and contains the olfactory organ. It provides air for respiration, serves the sense of smell, conditions the air by filtering, warming, and moistening it, and cleans itself of foreign debris extracted from inhalations. The nose has two cavities, separated from one another by a wall of cartilage called the septum. The external openings are known as nares or nostrils.

The Nasal Cavity The nose is an olfactory and respiratory organ. It consists of nasal skeleton, which houses the nasal cavity. In this article, we shall look at the applied anatomy of the nasal cavity, and some of the relevant clinical syndromes.his is carried out by the olfactory nerves. The olfactory bulb, part of the brain, lies on the superior surface of the cribriform plate, above the nasal cavity. Branches of the olfactory nerve run through the cribriform plate to provide special sensory innervation to the nose.

The Nasal Cavity The nasal cavity is the most superior part of the respiratory tract. It extends from the vestibule of the nose to the nasopharynx, and has three divisions: Vestibule – the area surrounding the anterior external opening to the nasal cavity. Respiratory region – lined by a ciliated psudeostratified epithelium, interspersed with mucus-secreting goblet cells. Olfactory region – located at the apex of the nasal cavity. It is lined by olfactory cells with olfactory receptors.

The Nasal Cavity Openings into the Nasal Cavity. One of the functions of the nose is to drain a variety of structures. Thus, there are many openings into the nasal cavity, by which drainage occurs. The paranasal sinuses drain into the nasal cavity. The frontal, maxillary and anterior ethmoidal sinuses open into the middle meatus.

Anatomy and Physiology of the Nasal Cavity (Inner Nose) and Mucosa Introduction. The nasal cavity refers to the interior of the nose, or the structure which opens exteriorly at the nostrils. It is the entry point for inspired air and the first of a series of structures which form the respiratory system.natomy of the nasal cavity. 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 which shapes and separates the nostrils.
