A 7-year-old girl complains of abdominal pain in

the evening before going to bed, the pain is localized to the area around the

navel. Her parents send her to bed saying that she will definitely feel better

in the morning. Unfortunately, the condition has not improved till morning. The

girl has a fever, vomits and the pain, which is now more intense, has moved to

the right hypogastrium (right lower abdomen, projection of pain from the right

iliac fossa). Her parents take her to surgery, where she is quickly diagnosed

with appendicitis, an inflammation of the appendix. The girl is operated on the

same day and the inflamed appendix is removed and sent for histological

examination. In which figure can we see the typical structure of the appendix?
