Phonetic Transcription

/ˌæksəˈniːmə/

Meaning and Usage

The term "axonema" refers to the structural core of cilia and flagella, typically composed of a microtubule arrangement in a "9+2" pattern. This arrangement consists of nine pairs of microtubules arranged in a circle around two central microtubules, fundamental to the function and movement of these organelles in cellular biology.

The frequency of use is relatively specialized, primarily found in biological and scientific contexts, particularly in discussions pertaining to cell biology and the structure of eukaryotic cells. It is more common in written contexts, especially in scientific literature, as opposed to casual oral speech.

Example Sentences

1. The axonema of the sperm cell's flagellum is crucial for its motility.

2. (Translation: Axonema de la flagelă a celulei spermatozoide este esențial pentru motilitatea acesteia.)

3. Disruptions in the axonema can lead to infertility in many organisms.

4. (Translation: Perturbările în axonema pot duce la infertilitate în multe organisme.)

5. Researchers are studying the axonema to develop new treatments for ciliary dyskinesia.

6. (Translation: Cercetătorii studiază axonema pentru a dezvolta noi tratamente pentru discinezia ciliară.)

Idiomatic Expressions

While "axonema" is a specialized term and not commonly used in idioms, it can be discussed in the context of biological terms and phrases relevant to cellular structure and function.

1. The axonema must be intact for the ciliates to maintain their swimming pattern.

2. (Translation: Axonema trebuie să fie intact pentru ca ciliatele să-și mențină modelul de înot.)

3. Understanding the axonema is key to deciphering how flagellar propulsion works.

4. (Translation: Înțelegerea axonema este cheia pentru a descifra cum funcționează propulsia flagelară.)

5. The integrity of the axonema is vital for the proper functioning of the respiratory tract.

6. (Translation: Integritatea axonema este vitală pentru funcționarea corectă a tractului respirator.)

Etymology

The term "axonema" is derived from the Greek words "axon," meaning "axle" or "axis," and "nema," meaning "thread." This reflects its structural function as the central framework of cilia and flagella.

Synonyms and Antonyms

Synonyms: microtubule arrangement, ciliary structure
Antonyms: There are no direct antonyms, as "axonema" refers to a specific structural entity within cells.
