- For example, things like allergies can cause nasal obstruction. Another very common cause of nasal obstruction is narrow nasal passages. Often, narrow nasal passages are the result of problems with the nasal septum and turbinates. The nasal septum and the turbinates are normal parts of the nose. The nasal septum is the structure that divides your nasal passages into the right and left sides. A deviated septum refers to a septum that is crooked. The turbinates are also inside the nose, near the septum.

- Nasal turbinates. The sinuses empty into the nasal passageways. Positioned along these passageways are long cone-like bony structures rich in blood vessels called the nasal turbinates. The turbinates are divided into the lower, middle and upper turbinates. Similar to the nasal and sinus membranes, the nasal turbinates are coated with mucus.

Deviated Septum Repair (septoplasty) Repair of a Deviated Septum (Septoplasty) - Surgery Overview. The nasal septum is the wall between the nostrils that separates the two nasal passages. It supports the nose and directs airflow. The septum is made of thin bone in the back and cartilage in the front. A deviated septum occurs when the cartilage or bone is not straight. A crooked septum can make breathing difficult. The condition also can lead to snoring and sleep apnea.

The Respiratory System - Design: parts of the respiratory system The nose and nasal cavity. The nose is the only external part of the respiratory system. It is made of bone and cartilage (tough connective tissue) and is covered with skin. The two openings to the outside, called nostrils, allow air to enter or leave the body during breathing.

Deviated Septum Causes and Solutions Your nasal septum is the wall inside your nose that divides your nasal cavity in half. Ideally, this wall, which is made out of cartilage and bone, runs directly through the midline of your nasal cavity, separating it into two equally sized passageways. If you have a deviated septum, your nasal septum is off-center. Some otolaryngologists (ear, nose, and throat specialists) estimate that the nasal septum is at least slightly off-center in 80 percent of the population.

Anatomy and Physiology of the Nasal Cavity (Inner Nose) and Mucosa The posterior two-thirds of the cavity is lined with pseudostratified columnar ciliated epithelium (a type of epithelium in which cells arrange themselves in columns and project tiny hairs called cilia) containing goblet cells (mucus producing cells), and which overlies a basement membrane.he 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.

Nasal cavity 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.n the sides of the nasal cavity are three 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.

Nose 1 The nose has two cavities, separated from one another by a wall of cartilage called the septum. 2  The shape of the nasal cavity is complex. 3  In the olfactory (smelling) portion of the nose, most of the lining is mucous membrane. A small segment of the lining contains the nerve cells that are the actual sensory organs. Fibres, called dendrites, which project from the nerve cells into the nasal cavity, are covered only by a thin layer of moisture.

Understanding Your Nasal Turbinates Structure (Anatomy) of the Nasal Turbinates (Conchae) As noted, the nasal turbinates are broken down into three sections, the upper, middle, and lower conchae. Inferior Meatus (Lower Conchae) The inferior meatus is the space between the floor of the nasal cavity and the inferior turbinate. This is the largest of the air spaces.

Nasal Anatomy The nasal cavity is divided by a vertical partition (the “nasal septum”) into a right and left side. The nasal septum is made up of cartilage (quadrangular cartilage) towards the front of the nose, and bone towards the back.he inferior turbinate is the largest of the three paired turbinates, and runs along the entire length of the lateral nasal wall, adjacent to the nasal floor. Sometimes, the inferior turbinate can get enlarged due to allergy or irritation, and can cause nasal blockage and a runny nose.

The Nasal Skeleton The skeleton of the nose is formed by three structures; bone, cartilage and fibro-fatty tissue. When looking at the scaffolding of the nose, it is useful to divide the structures into two parts; the external nasal skeleton and internal nasal septum. © 2015 TeachMeAnatomy.com [CC-BY-NC-ND 4.0].

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 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.

Understanding Your Nasal Turbinates Turbinates or Nasal Conchae. Turbinates, which are also called nasal concha or conchae (plural), are a network of bones, vessels and tissue within the nasal passageways that are responsible for warming, humidifying, and filtering the air we breathe. Normally there are 3 turbinates including: superior (upper), middle, and inferior (lower).

The function of the nasal conchae is? Please listen to either Nick N or me. The answer is D! A-the perpendicular plate of the ethmoid bond and the vomer bone divide the nasal cavity into a right and left side and it is called the septum (as in I have a a deviated septum). B-The conchae are bones stuck to the sides of the nasal cavity.
