The largest exhibition of Leonardo da Vinci's drawings of the human body is on display at the Queen's Gallery at Buckingham Palace.
During his lifetime, Leonardo made thousands of pages of notes and drawings on the human body. He wanted to understand how the body was composed.
Clinical anatomists believe that Leonardo's anatomical work from the 1500s was hundreds of years ahead of its time, and in some respects it can still help us understand the body today.
Rosie and Helen tell us more about this event in this week's On the Town.
