Tiny hairs on the outer wall of cells can move in different directions. In this process, neighboring hairs influence each other.
Tiny hairs on the outer wall of cells can move in different directions. In this process, neighboring hairs influence each other. Tiny hairs on our cell walls can move together and thus pump fluid. Now they have succeeded in developing a physical theory of these hairs' movements . They are just very simple structures, but without them we could not survive: Countless tiny hairs are found on the outer wall of some cells, for example in our lungs or even in our brain. When these micrometer-sized hairs coordinate their movement and produce wave-like motions together, they can cause currents on a microscale and thus pump fluid from one place to another. Paramecia - single-celled organisms with numerous cilia-like hairs - also use such effects to move around.
