What is the characteristic microtubule arrangement in the axoneme of a motile cilium?
Show answer and explanation
Correct answer: 9 doublets and 2 central singlets
Motile cilia feature a '9+2' arrangement, consisting of nine peripheral microtubule doublets surrounding two central singlet microtubules. This structure is essential for the mechanical bending required for ciliary movement.
