I remember reading that smoking paralyzes the cilia in your lungs (or, apparently, windpipe). --Jack ( Cuervo) 11:41, 30 August 2005 (UTC)
There is plenty of info here on the structure of Cilia but ridiculously little on their function.
The mechanism of Intraflagellar transport constructing cilia has now become a focus of attention, as discussed in some detail here. Apparently a Jekely and Arendt (2006) cilium evolution paper p. 193 describes Plasmodium falciparum as an exception that lacks IFT – "species with cilia that do not rely on IFT (in the parasite Plasmodium cilia assemble in the cytoplasm(48))". I've added a brief mention of this, using the panda's thumb link as I don't have access to the paper or the expertise to work from it. .. dave souza, talk 19:43, 6 August 2007 (UTC)
Adv. Biology is hard. I blinked and was a half a chapter behind.
PS. Write an interesting response.
Cilia of the nasal cavity consist of cells that form microscopic strands in the nasal passages that moisten the inhaled air (via mucosa), warm it, and trap foreign objects that flutter in its stream. [1] Healthy cilia beat in a coordinated backward-&-forward motion on an average of sixteen times per second, unlike nasal hairs that have no coordinated motion. They draw mucus up from the epithelium by capillary action to maintain humidity in the nasal passages. This is accomplished by trapping moisture in exhaled air and humidifying its evaporation via inhaled air. Also unlike nasal hairs, ciliated cells push mucus back in towards the oropharynx where it can be either swallowed or ejected. This mechanism is much like the system by which cilia in the ear canal remove cerumen and other detritus; visible ear hairs have no such use.
Cilial motility regularly declines with advancing age, a fact that may be implicated in the higher incidence of respiratory infections in this group of individuals. citation needed\
I totally agree. Biology is very hard. I thought that studying the cell was the hardest chapter. Our teacher actually made us take a test on how to hold a microscope.-- 69.196.197.190 ( talk) 02:18, 20 November 2008 (UTC)
The present article reads: Along with flagella, they make up a group of organelles known as undulipodia. I thought that cilia are structurally identical to flagella. —Preceding unsigned comment added by 91.64.166.91 ( talk) 12:18, 2 July 2008 (UTC)
If someone is going to write something on the scientific history, it may be interesting to know that it was discovered in 1898, and the article that is usually referenced, is "Beiträge zur Kenntnis einiger Drüsen und Epithelien" by Zimmerman in "Archiv für mikroskopische Anatomie", 9, pp. 163-168. Probably ISSN 0176-7364 or ISSN 0176-7356. I haven't been able to get it online, yet. -- WvEngen ( talk) 10:09, 29 July 2008 (UTC)
There is a misconception that primary cilia are non-motile. Primary cilia refers to the structure of an axoneme WITHOUT the central pair, i.e. 9+0. -- kupirijo ( talk) 12:22, 25 March 2009 (UTC)
The article has cilia length as 5-10 micrometres, but the length is given as 2-3 in the histology texts I have to hand [e.g., Junqueira & Carneiro]. Can someone confirm this? —Preceding unsigned comment added by 193.1.104.2 ( talk) 13:45, 9 July 2009 (UTC)
I am removing this image again. I think that this image would be very confusing for a lay reader, especially without any labels. For someone who doesn't know any better, they would probably confuse the bands of connective tissue as the "cilia" in the picture without knowing to look at the apical surface of the cyst. And even they, you can't see the cilia at the apical surface very well. Is this the best light micrograph we have access to in order to represent cilia to the wikipedia reader? I think we should keep looking.-- AaronM ( talk) 10:06, 20 August 2009 (UTC)
In the initial image, there is nothing labeling the axoneme. I presume that the purpose of the image is to illustrate the axoneme, but the reader would have to be an expert already to identify the axoneme in the image.
If it's not possible to alter the labeling within the image, the subscript text needs to be expanded so as to clarify which part is the axoneme. Since I am not an expert, I leave it to the author(s) to make the changes. Thanks. KC 20:25, 10 January 2016 (UTC)
Hello fellow Wikipedians,
I have just modified one external link on Cilium. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Due to the significance for the diagnostics of Covid-19 I would like to add a new section about the location of cilia in the human body (especially about the location in the nose itself). Does anybody know good sources for that? Greetings, Tresznjewski ( talk) 12:40, 11 April 2022 (UTC)
