centrosome
/ˈsɛntrəsəʊm
/noun Biology
An organelle near the nucleus of a cell which contains the centrioles (in animal cells) and from which the spindle fibres develop in cell division.A legacy of these ancient symbiotic interactions is that eukaryotic cells continue to show tight links between nuclei, centrosomes and microtubules in the form of Cell Bodies....
- In most animal cells, the centrosome contains a pair of centrioles, which consist of an array of microtubules.
- At metaphase, centrosomes initiate the bipolar microtubule spindle.
Origin
Late 19th century: from Latin centrum (see centre) + Greek sōma 'body'.
