The setae are extended and contracted in sequence to match the movement of the body.
Do ants have brains?
Ants have a main brain and several smaller brains that run along the length of their bodies called, "ganglia". The ganglia are little assistant brains to the main brain. The brain inside the ants head controls things like smell, sight and touch, but the smaller brains control, to some degree movement of the ant. Have you ever noticed that an ant will continue to twitch if you step on it? Even if the head is separated from the ants body, the legs will still twitch. This is because the smaller brains (ganglia) are still telling the ants legs to move!
