The hepatic diverticulum originates as an outgrowth from which primitive gut region?

• A. Foregut
• B. Midgut
• C. Hindgut
• D. Neural tube

Answer: (A)

During early development, the liver begins as an outgrowth of the foregut endoderm, called the hepatic diverticulum. This hepatic bud emerges from the caudal part of the foregut and grows into the surrounding mesenchyme, giving rise to hepatocytes and the biliary system, including the gallbladder and bile ducts. The foregut is the origin of the upper digestive structures (esophagus, stomach, proximal duodenum) plus these hepatic derivatives, whereas the midgut and hindgut form other portions of the intestine, and the neural tube is a separate structure. So, the hepatic diverticulum originates from the foregut.
