What is the "9+2" arrangement in the eukaryotic flagella?
- Cilia and flagella are protrusions from some cells that help for cellular locomotion.
- Cilia and flagella have a core composed of microtubules connected to the plasma membrane arranged in what is known as a 9 + 2 pattern. (a ring of nine microtubule doubles )
- This 9 + 2 organization allows the sliding of the microtubule doubles against one another to bend the cilia or flagella.
- This type of organization is found in most eukaryotic cilia and flagella.
