When you uphold something, you stick up for or support it. Police officers are paid to uphold the law, and crazy Elvis fans uphold their belief that he's still alive out there somewhere. If you reverse the two parts of this word, you get hold up. And that's exactly what upholding is: holding up or supporting an idea or practice. You might uphold your dog's innocence, even though it's pretty obvious he dug up the neighbor's flower bed.

A cilium (Latin for eyelash; the plural is cilia) is an organelle found in eukaryotic cells. Cilia are slender protuberances that project from the much larger cell body. There are two types of cilia: motile cilia and non-motile, or primary cilia, which typically serve as sensory organelles.In eukaryotes, motile cilia and flagella together make up a group of organelles known as undulipodia.Eukaryotic cilia are structurally identical to Eukaryotic flagella, although distinctions are sometimes made according to function and/or length.otile cilia are usually present on a cell's surface in large numbers and beat in coordinated waves. 1  In humans, for example, motile cilia are found in the lining of the trachea (windpipe), where they sweep mucus and dirt out of the lungs.
