The Nasal Bone The nasal bone is a bilateral symmetrical paired bone of the face. Their superior borders and main bodies form the bridge of the nose while the inferior borders connect with the nasal cartilage to form the superior margin of the nasal aperture.he nasal bones are ossified intramembranously via the cartilaginous nasal capsule. Clinically the hypoplasia or absence of nasal bones is a common feature in Down syndrome (trisomy 21) and other chromosomal abnormalities.

Nasal Cavity - Anatomy & Physiology The nasal cavity is occupied to a large extent by nasal conchae. These are turbinate bones which project into the nasal cavity with the purpose of supporting the olfactory mucus membranes and increasing the respiratory surface area, creating turbulence within the passing air.he nasal cavity is occupied to a large extent by nasal conchae.

Nasal Valve Collapse and Treatment Nasal Valve Collapse and Treatment. Nasal valve collapse is a breathing disorder that can result in severe nasal congestion, snoring and mouth breathing. Many doctors do not always pinpoint nasal valve collapse as the chief cause of sinus issues, so it is important that you explain all of your symptoms to your ENT or sinus specialist. You should have a list of your medications and disclose any previous nose surgeries, especially past rhinoplasties.

A/P Describe the bony features of the nasal cavity. The nasal cavity is mostly formed by the union of the maxillae. The ethmoid bone is at the rood of the nasal cavity. The perpendicular plate of the ethmoid and the vomer make the bony septum dividing the nasal activity into right and left sides. On the lateral walls of the maxillae are the inferior nasal conchae.

Nasal septum The nasal septum separates the left and right airways in the nose, dividing the two nostrils. It is depressed by the depressor septi nasi muscle.

Croup Croup can be caused by a number of viruses including parainfluenza and influenza virus. Rarely is it due to a bacterial infection. Croup is typically diagnosed based on signs and symptoms after potentially more severe causes such as epiglottitis or an airway foreign body have been ruled out. Further investigations—such as blood tests, X-rays, and cultures—are usually not needed.

Nasal concha Illustration of Upper Respiratory System. In anatomy, a nasal concha (/ˈkɒnkə/), plural conchae (/ˈkɒnki/), also called a turbinate or turbinal, is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various animals.

Nasal Obstructions A nasal obstruction is anything that impedes the flow of air into and out of the nose. The obstruction may block one or both of the nasal passages. Most cases of nasal obstruction are temporary, caused by sinusitis, allergies, birth control medication, or overuse of nasal sprays. The blockage may also be caused by an anatomical factor, such as a deviated septum, enlarged adenoids, nasal polyps, turbinate bones, or foreign objects.

Inferior nasal concha Superior to inferior nasal concha are the middle nasal concha and superior nasal concha which arise from the cranial portion of the skull. Hence, these two are considered as a part of the cranial bones.It has two surfaces, two borders, and two extremities.hey are also termed 'inferior nasal turbinates' because they function similar to that of a turbine: As the air passes through the turbinates, the air is churned against these mucosa-lined bones in order to receive warmth, moisture and cleansing.

Nasal cavity The nasal cavity (or nasal fossa) is a large air filled space above and behind the nose in the middle of the face.Each cavity is the continuation of one of the two nostrils.ilia and mucus along the inside wall of the nasal cavity traps and removes dust and pathogens from the air as it flows through the nasal cavity. The cilia move the mucus down the nasal cavity to the pharynx, where it can be swallowed.

- The nasal cavity is the chamber between external and internal nares. Coiled, shelf-like extensions of bones called conchae (a.k.a. turbinates) extend from the lateral walls of the nasal cavity toward the nasal septum. Narrow passageways between the conchae are called meatuses.The air that passes through the meatuses is filtered, warmed and humidified.oiled, shelf-like extensions of bones called conchae (a.k.a. turbinates) extend from the lateral walls of the nasal cavity toward the nasal septum.

SOUTH HOUSTON, TX City Hall. South Houston is adjacent to Pasadena, two miles southeast of the intersection of Interstate Highway 45 and State Highway 3, in southeastern Harris County. The town was named Dumont when it was founded in 1907 by C. S. Woods of the Western Land Company.

Anatomy of the human nose The nasal root is the top of the nose, forming an indentation at the suture where the nasal bones meet the frontal bone. The anterior nasal spine is the thin projection of bone at the midline on the lower nasal margin, holding the cartilaginous center of the nose.

Human nose Because of the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infections from the nasal area to spread to the brain. For this reason, the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla, is known to doctors as the danger triangle of the face.

nose The nostrils, which form the external entrance of the nose, lead into the two nasal cavities, which are separated from each other by the nasal septum, a partition formed of cartilage and bone. Three bony ridges project from the outer wall of each nasal cavity and partially divide the cavity into three air passages.

- The nasal septum, the division between the left and right airways of the nose, is made of three structures: the vomer bone, perpendicular plate of ethmoid bone, and its cartilage.

What is a Turbinate Reduction? The nasal turbinates are bony structures covered by a mucous membrane lining the inside of the nose. There are 3-4 turbinates on each side of the nose (inferior, middle, superior, and sometimes supreme).

- In the midline of the anterior surface of the maxilla is found a prominence, called the anterior nasal spine, with a lateral concave rim, called the nasal notch, that forms the floor of the piriform aperture.

rhinoplasty The strip of skin separating the nostrils is called the columella. Surgical approaches to nasal reconstruction are varied. Internal rhinoplasty involves making all incisions inside the nasal cavity. The external or open technique involves a skin incision across the base of the nasal columella.
