What do you call the gesture of raising both hands while shrugging your shoulders?

If somebody asks a question and you have no answer for it, then you can shrug your shoulders and move your hands up (with the palms of your hands turned to the sky).

Is there a word for what you do with your hands? It seems like an apologizing gesture people often do.
