Cilia Meaning: Definition, Examples, and Translations
๐ฆ
cilia
[หsษชl.i.ษ ]
Definition
cell structure
Cilia are microscopic, hair-like structures that extend from the surface of many types of cells. Their primary function is to facilitate movement and sensory functions in organisms. In multicellular organisms, cilia can help move fluids across the cell surface or propel single-celled organisms through their environments. The presence of cilia is crucial for various physiological processes, including the movement of mucus in the respiratory tract and the transport of eggs within the female reproductive tract.
Synonyms
Examples of usage
- Cilia play a key role in the respiratory system.
- The paramecium swims using its cilia.
- Cilia help clear debris from the lungs.

Interesting Facts
Biology
- Cilia are found on many types of cells, particularly in the respiratory tract, where they help clear out dust and pathogens.
- In certain unicellular organisms, cilia allow them to swim and navigate through water, acting like tiny oars.
- There are two main types of cilia: motile, which help with movement, and non-motile, which often serve sensory functions.
Health
- Dysfunctional cilia can lead to health issues such as respiratory infections due to their role in cleaning the airways.
- Certain genetic disorders, like primary ciliary dyskinesia, can impact the function of these structures, leading to severe lung problems.
Technology
- Researchers are exploring how cilia can inspire new technologies, like designing micro-robots for medical purposes.
- The study of cilia is contributing to advancements in nanotechnology, particularly in drug delivery systems.
Pop Culture
- Cilia made an appearance in educational cartoons, depicting tiny creatures that use them to swim around their microscopic worlds.
- In video games, some characters are inspired by microscopic life forms showcasing ciliaโs movement to navigate through their environments.
Origin of 'cilia'
Main points about word origin
- The term 'cilia' comes from the Latin word 'cilium,' meaning 'eyelash,' reflecting their hair-like structure.
- This word has been in use in English since the late 19th century, showcasing its scientific roots in biology.
The word 'cilia' comes from the Latin word 'cilium', which means 'eyelid' or 'eyelash.' This etymology is reflective of the structure's hair-like appearance. Cilia were first described in scientific literature during the 17th century, as early microscopes allowed scientists to observe them in various organisms. Initially observed in single-celled organisms, cilia have been found to have essential functions in multicellular animals as well. Over the years, cilia have been studied extensively in fields such as cellular biology, medicine, and genetics, revealing their importance in both health and disease.
