Cilia

Cilia are small, hairlike structures found on the surface of cells. They are composed of microtubules, meaning they are highly mobile. Cilia play an important role in many different processes, including movement, sensory detection, and fluid transport. They have the ability to beat in unison and create currents in the fluid around them. This is particularly important in the lining of airways and other bodily systems, as it helps to move dust, mucus, and other particles away from the body. Cilia also enable cells to detect direction, allowing them to swim and migrate. They are especially important in development, as they help to maintain the positioning of organs in the body.
