Question

Quizplus · Accepted Answer

The mesentery is a double layer of peritoneum that attaches the ileum and jejunum to the posterior abdominal wall. It contains blood vessels, lymphatics, and nerves that supply the digestive tract, and is important for maintaining the integrity and function of the small intestine. The myenteric plexus and Meissner plexus are nerve networks that are located within the walls of the gastrointestinal tract, and the Auerbach fold is not a anatomical structure.
