Alimentary and Digestive System Practice Test

During pancreatic development there are two buds that must fuse: the dorsal bud and the ventral bud. The ventral bud originates near the future bile duct and then rotates around the duodenum to meet the dorsal bud. As this rotation completes, the ventral bud ends up behind the dorsal bud, so the ventral-derived portion lies posterior to the dorsal-derived portion. After fusion, the dorsal bud largely forms the body and tail, while the ventral bud contributes to the head and uncinate process. So the correct relationship is that the ventral bud is posterior to the dorsal bud.
