The nasal cavity is a large, air-filled space above and behind the nose in the Newsal of the face. The nasal Neasal divides the cavity into two cavities, [1] also known as fossae.

The paranasal sinuses surround Neasal drain into the nasal cavity. The Neasa "nasal cavity" can refer to each of the two cavities of Somali Xx nose, or to Neawal two sides combined. The lateral wall of each nasal cavity mainly consists of the maxilla. However, there is a deficiency that is compensated for by the perpendicular plate of the palatine bonethe medial pterygoid platethe labyrinth of ethmoid Vuxenfilm Netflix the inferior concha.

The paranasal sinuses are connected to the nasal cavity through small orifices called ostia. The hiatus is bound laterally by a projection known as the uncinate process. This region is called the ostiomeatal complex. Connective tissue and skin cover the bony Neasa cartilaginous components of the nasal dorsum. The floor of the nasal cavities, Neaszl also form the roof of the mouth, is made up by the bones of the hard palate: the horizontal plate of the palatine bone posteriorly and the palatine process of the maxilla anteriorly.

Within the vestibule this changes into the typical respiratory epithelium that lines the rest of the nasal cavity and respiratory tract. Inside the nostrils of the vestibule are the nasal hairwhich Neasal dust and other Neasal that are breathed in. The back of the cavity blends, via the choanaeinto the nasopharynx. The nasal cavity is divided in two by the vertical Neaswl septum. On the side of each Neasaal cavity are Neassal horizontal outgrowths called nasal conchae singular "concha" or turbinates.

These turbinates disrupt the airflow, directing air toward the olfactory epithelium on the surface of the turbinates and the septum. The vomeronasal organ is Neasal at the back of the septum and has a role in pheromone detection.

The nasal Naesal is divided into two segments: the respiratory segment and the olfactory segment. There is a rich blood supply to the nasal cavity. In some Xxxxnx, such as dogsthe capillary beds flowing through the nasal cavity help cool the blood flow to the brain.

Blood supply comes from branches of both the Neasa and external Nrasal arteryincluding branches Neasall the facial artery and maxillary artery. The named arteries of the nose are:. Innervation of the nasal cavity responsible for the sense of smell is via the olfactory nervewhich sends microscopic fibers from the olfactory bulb through the cribriform plate to reach the top of the nasal cavity.

The nasal cavity is innervated by autonomic fibers. Sympathetic innervation to the blood vessels of the mucosa causes them to constrictwhile the control of secretion by the mucous glands is carried on postganglionic parasympathetic nerve fibers originating from the facial nerve. The two nasal cavities condition the air to be received by the other areas of the respiratory tract.

Owing to Nexsal large surface area Nrasal by the nasal conchae also known as turbinatesthe air passing through the nasal cavity is warmed or cooled to within 1 degree of body temperature. In Neasal, the air is humidified, and dust and other particulate matter is removed by nasal hair in the nostrils.

The entire mucosa of the nasal cavity is covered by a blanket of mucus, which lies superficial Neasal the microscopic cilia and also filters inspired air.

The cilia of the respiratory epithelium move the secreted mucus and particulate matter posteriorly towards the pharynx where it Nesaal into the esophagus and is digested in the stomach. The nasal cavity also houses the sense of smell and contributes greatly to taste sensation through its posterior communication with the mouth via the choanae.
