Question

Sphincter of Oddi occurs between

• A. Pylorus and duodenum
• B. Oesophagus and stomach
• C. Large intestine and small intestine
• D. Ampulla of vater and Duodenum

Answer 1

The correct option is D Ampulla of vater and Duodenum

Solution: The ampulla of Vater is located where bile duct and pancreatic duct join and empty into small intestine. The Sphincter of Oddi is a concentric ring of muscle originating from the pre-ampullary portion of the bile and pancreatic ducts. Initially it is found in the junction between the duodenal wall and the bile and pancreatic ducts.

So the correct answer is "Ampulla of vater and Duodenum".
