Definition of axoneme in English:

noun

Biology
The central strand of a cilium or flagellum. It is composed of an array of microtubules, typically in nine pairs around two single central ones.
Example sentences
  • Furthermore, isolated mutant axonemes lacking the central pair or radial spokes can vigorously beat in certain nonphysiological solutions.
  • There are nine paired microtubules per axoneme, and they are interconnected by dynein molecules, protruding at regular intervals like the legs of a millipede.
  • It brings us to another question, whether the neck region of a flagellar axoneme with a basal body could make some mechanical hindrance to microtubules sliding.

Origin

early 20th century: from Greek axōn 'axis' + nēma 'thread'.

adjective
Example sentences
  • The PCD phenotype results from axonemal abnormalities and dysfunction of motile cilia and flagella.
  • Though speculative, perhaps these heterodimeric motors walk along the seam of the doublet microtubules or interact optimally with the microtubule-associated proteins found on axonemal microtubules.
  • Previous studies have revealed that axonemal microtubules showed oscillatory sliding under the condition where the free bending of axonemes was restricted by adhering them on glass surfaces.
