Question

Axonemal microtubules A) are highly disorganized but very stable. B) may be loosely associated with basal bodies. C) are organized around a central shaft or axoneme. D) are required to maintain axons. E) did not become clearly recognized until better fixation techniques became available in the 1960s.

Answer 1

The correct option is C). Axonemal microtubules are organized around a central shaft or axoneme.

Step-by-step explanation:

The axoneme is formed by a stable cytoskeletal structure of cilia and flagella, consisting of microtubules, of which 9 are double peripheral microtubules, accompanied by their associated proteins (these proteins helps to maintain axonemal microtubules organization) and a pair of central microtubules (the structure is known as 9+2 axoneme too). The axoneme functions as the organizing center of the microtubules (the microtubules are organized around it), it extends out of the cell surface and its flexion allows the movement of the cilia and flagella.
