Learning Activity 2

  1. Describe how elongation and rotation of the simple primitive tube establish the gut anatomy.
  2. Explain the developmental processes of elongation, herniation and rotation of the mid-gut.
  3. Describe the structure of the attachment of the gut to the body wall.
  4. Identify the developmental origins of abnormalities of the gut lumen, innervation, herniation and malrotation.

1. Mechanical Changes

In the second trimester, the ventral and dorsal mesenteries associated with the stomach are still anatomically different from the newborn. The figure shows a lateral view of this process comparing the early second trimester arrangement with the newborn structure.

Pancreas rotation.jpg After the stomach the initial portion of the gastrointestinal tract tube is the duodenum which initially lies in the midline within the peritoneal cavity.

This region, along with the attached pancreas, undergoes rotation to become a retroperitoneal structure.

This diagram shows the rotation with spinal cord at the top, vertebral body then dorsal aorta then pertioneal wall and cavity.
