Eukaryotic cilia and flagella have an internal structure of microtubules in a "9+2" arrangement. This arrangement consists of
- Acheck_circle
9 microtubule doublets surrounding 2 central singlets
- B
9 microtubule singlets surrounding 2 central doublets
- C
11 randomly arranged microtubules anchored to a basal body
- D
9 actin filaments surrounding 2 central myosin bundles
Explanation
The classic 9+2 axoneme: nine outer doublets ringing two central singlet microtubules.
