Question

An arrangement of microtubules located in the matrix of cilia and flagella is called the __________?

1) axial bundle
2) axial filament
3) axoneme
4) axillary tubule

Answer 1

The arrangement of microtubules in the matrix of cilia and flagella is called an axoneme, characterized by a "9 + 2 array" structural pattern.

Step-by-step explanation:

The arrangement of microtubules located in the matrix of cilia and flagella is called an axoneme. This structure is characterized by its "9 + 2 array" which consists of a ring of nine microtubule doublets (paired microtubules) that encircle two central singlet microtubules. The axoneme is critical for the movement and structural integrity of cilia and flagella, providing the tracks along which the motor proteins dynein and kinesin walk to facilitate motion.
