This secreted mucus covers the nasal cavities, and serves as a filter, by trapping air-borne particles larger than 2 to 3 micrometers. The respiratory epithelium also serves as a means of access for the lymphatic system, which protects the body from being infected by viruses or bacteria. Smell
The conchae provide, first and foremost, the humidity needed to preserve the delicate olfactory epithelium, which in turn is needed to keep the olfactory receptors healthy and alert. If the epithelial layer gets dry or irritated, it may cease to function. This is usually a temporary condition but, over time, may lead to chronic anosmia. The turbinates also increase the surface area of the inside of the nose, and, by directing and deflecting airflow across the maximum mucosal surface of the inner nose, they are able to propel the inspired air. This, coupled with the humidity and filtration provided by the conchae, helps to carry more scent molecules towards the higher, and very narrow regions of the nasal airways, where olfaction nerve receptors are located.The superior conchae completely cover and protect the nerve axons piercing through the cribriform plate (a porous bone plate that separates the nose from the brain) into the nose. Some areas of the middle conchae are also innervated by the olfactory bulb. All three pairs of conchae are innervated by pain and temperature receptors, via the trigeminal nerve (or, the fifth cranial nerve).
Tramadol/paracetamol, also known as tramadol/acetaminophen and sold under the brand name Ultracet, is a fixed-dose combination medication used for the treatment of moderate to severe pain. It contains tramadol hydrochloride and paracetamol. It is taken by mouth. References
