The peripheral doublets of the axoneme are connected to one another by interdoublet bridges composed of an elastic protein called nexin. Peripheral doublets are the nine double microtubules found at the periphery of the axoneme in cilia and flagella, while axoneme refers to the entire microtubule-based structure responsible for the movement of these structures. The peridoublet sheath and dynein are also parts of the axoneme, but they are not involved in connecting the peripheral doublets to one another.
