The sphenoidal conchae (sphenoidal turbinated processes) are two thin, curved plates, situated at the anterior and lower part of the body of the sphenoid. An aperture of variable size exists in the anterior wall of each, and through this the sphenoidal sinus opens into the nasal cavity.

What is Sphenoidal sinus?

(SFEE-noyd SY-nus) A type of paranasal sinus (a hollow space in the bones around the nose). There are two large sphenoid sinuses in the sphenoid bone, which is behind the nose between the eyes. The sphenoid sinuses are lined with cells that make mucus to keep the nose from drying out.

What is the function of the Sphenoidal sinus?

Sinuses are air-filled sacs (empty spaces) on either side of the nasal cavity that filter and clean the air breathed through the nose and lighten the bones of the skull.

What is your sphenoid?

The sphenoid bone (wasp bone) is part of the base of the skull. An unpaired bone located in the cranium (or skull), the sphenoid bone, also known as the wasp bone, is located in the middle and toward the front of the skull, just in front of the occipital bone.

What are conchae?

The conchae are structures made of bone inside of your nose. They help control the airflow into your nose. They also clean and warm air that you’ve inhaled so that it’s ready to go to your lungs for respiration. Respiration is the process of breathing in and out.

What are posterior nasal apertures?

The choanae (singular choana), posterior nasal apertures or internal nostrils are two openings found at the back of the nasal passage between the nasal cavity and the throat in tetrapods, including humans and other mammals (as well as crocodilians and most skinks).

Where do maxillary sinuses drain?

The maxillary sinus (or antrum of Highmore) is a paired pyramid-shaped paranasal sinus within the maxillary bone which drains via the maxillary ostium into the infundibulum, then through hiatus semilunaris into the middle meatus. It is the largest of the paranasal sinuses.

What organs are in the Sphenoidal sinus?

The sphenoidal sinuses are situated back of the nose in the sphenoidal bone, which forms a forward part of the base of the skull and contains the depression, or fossa, for the pituitary gland.

What is a maxillary sinus?

The maxillary sinus is one of the four paranasal sinuses, which are sinuses located near the nose. The maxillary sinus is the largest of the paranasal sinuses. The two maxillary sinuses are located below the cheeks, above the teeth and on the sides of the nose.

Can you feel sinus pressure in the back of your head?

Pressure and pain from sinus congestion can be felt behind the forehead, eyes, cheeks or jaw, depending on which types of sinuses are affected.

What is the function of maxillary sinus?

The maxillary sinuses might simply serve to improve the respiratory function of the nose. A flow of inspiratory air does not occur. The maxillary sinuses are decisively involved in the production of nitrogen monoxide (NO) and thus in supporting the immune defense of the nasal cavity.

How do you relieve sinus pressure in your jaw?

Treating a Sinus Toothache Getting plenty of fluids helps to thin out the mucus and reduce blockages and pressure. Warm drinks can be especially helpful. Steam can also help to open up your sinuses and allow them to drain, so you might want to steam your face or take a hot shower.

Does the sphenoid bone contains a sinus?

Also, several fissures and foramina exist in the sphenoid, which transports several blood vessels and nerves of the skull to the head and neck. The body of the sphenoid has a cavity with a sinus that communicates with the nasal cavity.

What causes sphenoid sinus disease?

Sphenoid sinusitis can be caused by both bacterial and viral infections that impact the upper respiratory system. Other possible factors include a weakened immune system, tooth abscesses, nasal polyps, nasal defects and enlarged adenoids.

How do you clear a sinus sphenoid?

  2. Find the area between your nasal bone and the corner of the eyes.
  3. Hold a firm pressure in that spot with your fingers for about 15 seconds.
  4. Then, using your index fingers, stroke downward along the side of the bridge of your nose.

What are conchae in anatomy?

The nasal conchae or turbinates are long, narrow curled shelves of bone that protrude into the nasal cavity. The superior, middle and inferior conchae divide the nasal cavity into four groove-like air passages.

What is another name for conchae?

In anatomy, a nasal concha (/knk/), plural conchae (/knki/), also called a nasal 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.

What is conchae and its function?

nasal concha, also called Turbinate, or Turbinal, any of several thin, scroll-shaped bony elements forming the upper chambers of the nasal cavities. They increase the surface area of these cavities, thus providing for rapid warming and humidification of air as it passes to the lungs.

What is a turbinate in the nose?

Turbinates are small structures inside the nose that cleanse and humidify air that passes through the nostrils into the lungs.

Where is the anterior nasal spine located?

The anterior nasal spine (ANS) is a protrusion of the maxilla at the base of the nose. It is important in determining the morphology of the human face as regards support for the nasal tip and projection of the nose and the upper lip.

What are the names of the nasal cartilages?

There are five individual cartilages that make up the nasal cavity: septal nasal cartilage, lateral nasal cartilage, major alar cartilage (greater alar cartilage, or cartilage of the aperture), minor alar cartilage (lesser alar cartilage, sesamoid, or accessory cartilage), and vomeronasal cartilage (Jacobson’s …

What are the symptoms of maxillary sinusitis?

Signs and symptoms of sinusitis Pain, headache, nasal obstruction, a purulent nasal secretion and ‘postnasal drip’ (a discharge of ‘mucopus’ into the pharynx) are commonly found and there may also be fever and malaise. The pain is dull, heavy, throbbing and located over the cheek and in the upper teeth.

  2. Gently massage this area using a circular motion.
  3. Repeat for around 30 seconds to a minute.

What is the treatment for maxillary sinusitis?

Treatment of maxillary sinusitis should primarily consist of restoring the normal milieu within the sinus by antral puncture and lavage. Penicillin V is still the first antibiotic drug of choice, because of its effectiveness in vitro and in vivo.

Can sinus problems cause neck pain?

Yes, your neck can hurt from a sinus infection. Either your neck may be causing the sinus infection (which is relatively rare) or your sinus infection may be causing a tension headache which has extended into your neck.

What are the 4 paranasal sinuses?

Paranasal sinuses are named after the bones that contain them: frontal (the lower forehead), maxillary (cheekbones), ethmoid (beside the upper nose), and sphenoid (behind the nose).
