cytaster
Very LowHighly Technical/Scientific
Definition
Meaning
A structure formed during cell division, specifically around the centrioles, radiating microtubules like a star.
A term used in cell biology for the star-shaped system of microtubules (the aster) that forms around each centrosome during mitosis or meiosis; essentially synonymous with 'aster' in this specific cellular context.
Linguistics
Semantic Notes
The term is a compound of 'cyt-' (cell) and '-aster' (star), describing its appearance. It is almost exclusively used in detailed descriptions of the mechanics of cell division.
Dialectal Variation

Differences
No significant differences in meaning or usage. Spelling conventions (e.g., 'centred' vs. 'centered') do not apply to this term.
Connotations
None beyond its precise biological definition.
Frequency
Equally rare in both varieties, confined to advanced biology texts.

Examples
By Part of Speech
adjective
British English
- The cytaster formation was complete.
- Cytaster microtubules were labelled.
American English
- The cytaster formation was complete.
- Cytaster microtubules were labeled.
Examples
By CEFR Level
- The biologist drew a diagram showing the cytaster during cell division.
- In early prophase, the duplication of the centrosome leads to the formation of two distinct cytasters, which will organise the mitotic spindle.
Learning
Memory Aids
Mnemonic
Imagine a CELL (cyto-) forming a STAR (-aster) inside itself as it prepares to divide into two.
Conceptual Metaphor
A STAR (the cytaster) as an ORGANISING CENTRE from which forces (microtubules) radiate to pull the cell apart.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with general words for 'star' (звезда).
- It is a precise scientific term, not a descriptive phrase.
Common Mistakes
- Misspelling as 'cytster' or 'cyaster'.
- Using it in non-biological contexts.
- Confusing it with 'cytoplasm' or other 'cyto-' prefixed terms.

FAQ
Frequently Asked Questions
No, it is a very rare, highly specialised term used only in advanced cell biology.
In modern usage within cell biology, they are essentially synonymous. 'Cytaster' explicitly notes its cellular ('cyto-') context.
It would be highly unusual and almost certainly misunderstood unless you are speaking with a cell biologist about mitosis.
It is pronounced SY-tas-ter, with the primary stress on the first syllable 'SY'.
