Practice question
Question
Consider the following relationships within the axoneme of a eukaryotic cilium:
I. The two central microtubules are connected by bridges and enclosed by a central sheath.
II. Nine radial spokes connect the central region with the peripheral doublets.
III. Adjacent peripheral doublets are interconnected by linkers.
Which option correctly evaluates these statements?
Explanation
The central pair is connected by bridges and enclosed by a central sheath. Nine radial spokes extend towards the peripheral doublets, and the peripheral doublets are also interconnected by linkers. These relationships accompany the 9+2 axonemal arrangement.
