Human hands and feet are miracles of evolution, with our dextrous thumbs, in particular, one of the keys to the survival of the human race.
But how well do you really know the knobbly things at the ends of your wrists and ankles?
Our 15-question multiple choice quiz will test your knowledge of hands and feet to the limit, to the bones inside your hands and feet, to famous left-handed people.
We start off easy with a couple of questions which pretty much anyone should know from their general knowledge.
But stick with it and it gets MUCH harder, with some seriously tricky questions you might only know if you know a bit about human anatomy.
Try your luck below!
