 CELL BIOLOGY: ON THE FORMATION OF CILIA
1) The internal mechanism of cilia is among the most ancient biological motors on an evolutionary scale, producing beat patterns that consist of 2 phases: a) during the effective stroke, the cilium moves approximately as a straight rod, and b) during the recovery stroke, the cilium rolls close to the surface in a tangential motion.
At the present time, delineation of the detailed internal structure of cilia and the role of dynein arms in ciliary movement are the focus of research in a number of laboratories.
Although cilia and flagella are closely related structures, they can be distinguished from each other on the basis of differences in size, number, and pattern of movement.

 Computation of the Internal Forces in Cilia: Application to Ciliary Motion, the Effects of Viscosity, and Cilia ...
Machemer investigated the behavior of cilia when the fluid viscosity was increased by as much as 40 times that of water.
The motion of cilia and flagella is governed by the Stokes equations with no-slip boundary conditions on their surfaces and
of the cilia with respect to the direction of the effective stroke.

 Cilia
The other array of cilia is so hidden, so little known to almost everyone other than physicians and zoologists, it comes as a surprise to learn that cilia exist and function busily inside our brain and spinal cord.
Both men and women (and all other mammals) have cilia in two other places in their bodies.
When a human being is an early tiny embryo, long before the fetal stage, its nervous system is a simple hollow tube, little more than an in-folding of ciliated embryonic skin, or epithelium.

 Outlook: Cilia genes
In one such instance, most plants evolving to adapt from life in the sea to life on land discarded their cilia.
Studying Chlamydomonas allows Dutcher’s group to more easily isolate and manipulate cilia and basal bodies.
“Our hope is that we can now take our data set and accelerate the search for genes that contribute to some of the many human disorders that involve cilia and basal bodies.”

The beating of cilia is the primary method of moving mucus in healthy subjects.
Therefore, our multiscale numerical model, and our experimental measurements of cilia forces are intimately related to both roles of cilia, actuator and sensor, that constitute this project.
The thickness of the periciliary layer (PCL) is critical for effective propulsion of mucus by cilia.

 Animal Cells: Cilia and Flagella
Cilia and flagella's movement is controlled by the centrioles, also called "basal bodies." These basal bodies control the direction of the movement of the "fingerlike" cilia and flagella.
Humans contain both flagella and cilia, and a good example of cilia and flagella in a human body is in fertilizing a human egg.
These can all move and become the basal body of cilia or flagella.

 Cilia, flagella, and centrioles
Basal bodies control the direction of movement of the cilia.
Cilia and flagella have the same internal structure.
Note the experiment in your text that describes how the direction of movement was changed.

 CHEO — Child Health Information
The basic problem in Immotile Cilia Syndrome is that because the cilia fail to beat (or, less commonly, they fail to beat in an effective fashion), mucous fails to be cleared out of the respiratory passages.
Most of the treatments used for Immotile Cilia Syndrome have been "borrowed" from research on what are the best treatments for Cystic Fibrosis.
Cystic Fibrosis, like Immotile Cilia Syndrome, is a genetic condition, but it is considerably more common, with an incidence of 1 in 2,000 people.

 HHMI News: Researchers Snare New Cilia Genes
These subtypes include those that are motile — such as those found in sperm and lungs — and those of a type called “compartmentalized” that are key structures in sensory organs- including the senses of vision, hearing and olfaction.
The genes are considered important because of the ubiquity of cilia, which are critical for transport and sensory structures located throughout the human body — including the brain, nose, ears, eyes, lung, kidneys and sperm.
According to Zuker, the cilia genes they identified may prove important in understanding the causes of genetic diseases involving cilia.

 9 + 2 Arrangement
The movement of cilia and flagella is due to interactions between the peripheral microtubule doublets.
These interactions require energy in the form of ATP.

 Signals From a Hair Cell
The dance of the hair cell's cilia plays a vital role in hearing, Corey explains.
Together, the two researchers have helped discover how movements of the cilia, which quiver with the mechanical vibrations of sound waves, cause the cell to produce a series of brief electrical signals that are conveyed to the brain as a burst of acoustic information.
Now an HHMI investigator at MGH and Harvard Medical School, Corey was a graduate student at the California Institute of Technology when he began working with James Hudspeth, a leading authority on hair cells.

 Design Arguments for the Existence of God [Internet Encyclopedia of Philosophy]
Thus, there is no reason to think that it is logically or nomologically impossible, according to Darwinian theory, for a set of organisms with a precursor to a fully functional cilium to evolve into a set of organisms that has fully functional cilia.
Since, for example, a cilium-precursor (i.e., one that lacks at least one of a cilium's parts) cannot perform the function that endows a cilium with adaptive value, organisms that have the cilium-precursor are no "fitter for survival" than they would have been without it.
Organisms that have, say, a precursor to a fully functional cilium are no fitter than they would have been without it, but there is nothing in Darwinian theory that implies they are necessarily any less fit.

 Cilia and Cilia
“This will provide the basic foundation to understand how cilia form,” says Avidor-Reiss.
The discovery of these genes provides medical researchers with a critical new tool for diagnosing genetic diseases that involve cilia dysfunction and possibly for developing drugs that can minimize the effects of such dysfunctions.
Other widely known human cilia disorders include pulmonary diseases caused when respiratory cilia, which cleanse the lungs by sweeping mucous into the throat, are defective.

 cilia
These structures are found in all animalia except arthropods and nematodes.
The internal structure of a cilium is identical to that of a eukaryotic flagellum, and the terms are often used interchangeably.
In humans, cilia are found for example in the lining of the windpipe, where they sweep mucus and dirt out of the lungs, and in the oviducts, where they move the ovum from the ovary to the uterus.

 Cilia and Flagella
During the course of evolution, cilia have been adapted for other functions.
Flagella also tend to be longer than cilia but are otherwise similar in construction.

 Cilium - Wikipedia, the free encyclopedia
Cilia are found in all animals, although nematodes and arthropods only have non-motile cilia on some sensory nerve cells.
Biologists refer to this organization as a canonical "9 + 2" structure.
Cilia are structurally identical to eukaryotic flagella, and the two terms are often used interchangeably.

They also might lead to new drugs to minimize the health effects of such disorders.
In recent years, medical researchers have linked other diseases to the absence and dysfunction of cilia.
One example of the important roles cilia play is in human fertility.

 Malta Today: The Cilia chronicles
Joe Cilia had given the brief for the publishing of these contracts to Notary Joseph Debono who takes care of his professional practice while he is PS, when these contracts should have been published by the government’s own notary.
Cilia declares the PM did not find anything irregular in his actions but only that he admonished him into being more prudent.
Following Cilia’s appointment, the accounts for the pool were handed over to accountant Stephen McCarthy, whom The People claim is a personal friend and a well-known staunch supporter of Cilia.
