#1. A surgeon is performing an appendectomy on a child and notices a short and broad appendix at its junction with the caecum. What is the likely age of the patient undergoing surgery? ? The typical tubular structure of the appendix is formed by about the age of 2 years.
2 years
#2. A patient presents with appendicitis, and imaging reveals the appendix is in a pelvic position. What percentage of cases does this represent? ? In approximately 21% of cases, the appendix is in a pelvic position.
21%
#3. The appendicular artery, a branch of the lower division of the ileocolic artery, is a critical blood supply for the appendix. What happens if thrombosis occurs in this artery? ? Thrombosis of the appendicular artery can lead to necrosis of the appendix, also known as gangrenous appendicitis.
Necrosis of the appendix
#4. A surgeon is having difficulty finding the appendix during an operation. What anatomical feature can be used to locate the base of the appendix? ? Gentle traction on the taeniae coli, particularly the anterior taenia, can lead the surgeon to the base of the appendix.
Taeniae coli
#5. The vermiform appendix is present in humans, certain anthropoid apes, and the wombat. In which animals is the appendix absent? ? The vermiform appendix is absent in animals such as dogs, cats, horses, and rats.

#6. A surgeon is performing an appendectomy and notices a transparent mesoappendix in a pediatric patient. What can be observed in the mesoappendix in childhood? ? In childhood, the mesoappendix is often transparent, allowing the observation of blood vessels.

#7. The vermiform appendix is most frequently associated with which clinical syndrome? ? Acute appendicitis is the most common cause of an 'acute abdomen' associated with the vermiform appendix.
Acute appendicitis
#8. A patient is diagnosed with appendicitis, and imaging reveals an appendix lying in the left iliac fossa. What developmental abnormality may be responsible for this finding? ? Intestinal malrotation can lead to the appendix being found in unexpected locations, such as the left iliac fossa.
Intestinal malrotation
#9. What is the primary blood supply to the appendix, and which artery does it originate from? ? The appendicular artery, a branch of the lower division of the ileocolic artery, is the primary blood supply to the appendix.

#11. What is the putative role of the appendix in the pathogenesis of ulcerative colitis? ? Appendicectomy seems to be protective against the development of ulcerative colitis, suggesting a protective role of the appendix.
