Below are various images and videos of the voice in action.
The vocal cords are apart for breathing in. The rings of the trachea (wind pipe) can be seen. They are at their widest apart during a sniff.
With a constant light, the vocal cords blur once they are vibrating, but at the instant before they vibrate, the vocal cords can be seen in this shortened position, slightly bowed. The arytenoids have come together.
At a high pitch, at the onset of phonation, the vocal cords are stretched.
