The user had stopped browsing through the Scene at the shown frame. By clicking on the name "left kidney" in the List of Objects, while being in Paint mode, the organ was highlighted in green.
He was curious about the small vessel next to the kidney. He clicked on it with the right mouse button. The appearing popup menu told him that it was the "left inferior polar artery". In addition, he could learn that it belongs to the "left renal arteries" from the view point of Systemic Anatomy. The popup menu tells him also that it is branching from the "abdominal aorta".
The annotations were created by just clicking on the organs in the Scene window, or on their names in the List of Objects, while being in Annotate mode.
