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.
- As far as I can recall, they're responsible for the "tickle" when you need to cough, but I can't verify this or elaborate at all. --Johnny (Cuervo) 21:22, 8 May 2007 (UTC)
[edit] Plasmodium falciparum
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)
[edit] biology
Adv. Biology is hard. I blinked and was a half a chapter behind.
PS. Write an interesting response.
[edit] Some info moved from "nose hair"- please merge it if necessary
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]
