Question 4#

A pocket- or sock -like outpouching on the anti-mesenteric side of the distal ileum, called a Meckel diverticulum, is caused by:

A) Excessive traction on the intestine during childbirth
B) Increased intraluminal pressure
C) A persistent vitelline duct
D) A mutation of the c-Mec gene

Correct Answer is C

Comment:

The embryonic gut communicates with the yolk sac by mean of the vitelline duct. Failure of this structure to obliterate by the end of gestation can result in a Meckel diverticulum.
