The scroll shaped conchae increase the turbulance of air flowing through the nasal cavity. This swirling forces more of the inhaled air into contact with the war, damp mucosa and encourages trapping airborne particles (dust, pollen, bacteria) in the sticky mucus.

Basically, it is way too easy for the sinuses to become are inflamed and blocked.

What is the medical term meaning inflammation of the lining of the sinuses?

Sinusitis (sye-nuss-EYE-tiss) means inflammation of the sinuses or, more specifically, the lining of the sinuses. Inflammation of the sinuses means infection in the sinuses which causes frontal headaches and nasal discharge. There are two sinuses called maxillary sinus which are in the cheek bones and frontal sinus and para-nasal sinuses around the base of the nose. You may require antibiotics, nasal decongestants, antral washouts and sometimes surgery to treat difficult cases.

What is the difference between latent infection and inapparent infection?

An inapparent infection occurs when a susceptible person is exposed to an agent, is consequently infected, but neverdevelops clinical symptoms (subclinical). An inapparent infection may result in immunity - but they may not develop immunity and could even become a carrier.In contrast, an exposed susceptible person may develop symptoms (clinical infection), but later enter a period where they no longer exhibit those symptoms. This person would be said to have a "latent infection". They have not recovered - they are still infected -- and they might start to exhibit clinical symptoms later.Exposed ---- Infected ------ no symptoms --------------------------------------> Resolution INAPPARENT INFECTIONExposed ---- Infected ----- symptoms ----no symptoms ---- symptoms ----> Resolution|< Latent Infection>|- Dominick A.

Can an earache cause nausea dizziness or fatigue?

It wouldn't necessarily be the earache that would cause the dizziness, nausea and fatigue but rather it is most likely the cause of the earache that is having this affect. It actually sounds like typical symptoms of congested sinuses and a sinus infection. You see the sinuses are connected to the ear via the eustaschian tube. When the sinuses are cognested they create pressure in the head that can cause blocked ears or earaches, and when there is a sinus infection you may eve develop an ear infection. The dizziness can also be due to the pressure that is being created in the head by the sinuses. The farigue is a sign that there is an infection because an infection runs down the immune system leaving your body tired and weak. It also seems possible that the person could have post nasal drip, because of the nausea symptom. You see post nasal drip often occurs when the sinuses are congested. Post nasal drip happens when you can't drain mucus through the nose because your nose or your sinuses are blocked. So the mucus is drained down the back of the throat.
