D is the answer to this question. The greater omentum is also known as the omentum majus is a large fold that hangs from the stomach. Some have described it to look similar to an apron. The greater omentum is attached to the transverse colon.

This is in charge of connecting the stomach to the abdominal wall. If all of the choices will be considered, it is only letter D that will fit what the question is asking for. The other parts can be considered a part of the upper portion of the abdominal area like the lesser omentum which is located near the liver area.

The answer to this question is D. When the gut develops, two mesogastria are attached to the stomach. These two mesogastria are called the ventral mesogastrium and the dorsal mesogastrium. Each mesogastrium will be the “house” of different organs as they begin to develop.

The liver will develop in the ventral mesogastrium while the spleen and the pancreas will begin to grow at the dorsal mesogastrium. The greater omentum will also become part of the dorsal mesogastrium. The greater omentum is known to be a part of the organ that somehow resembles an apron. Its main function is to connect the stomach to the abdominal wall.

1. greater momentum-during the development of the gut, there are two mesogastria attaching to the developing stomach: the dorsal mesogastrium and the ventral mesogastrium. different organs begin to develop in each mesogastrium-the spleen and pancreas develop in the dorsal mesogastrium and the liver develops in the ventral mesogastrium. so, the structures involving the spleen and the posterior part of the developing stomach (which becomes the greater curvature) are derived from the dorsal mesogastrium. these include: the greater omentum (gastrophrenic ligament, gastrosplenic ligament, gastrocolic ligament) and splenorenal ligament. the structures involved with the liver and its attachment to the stomach wall form the ventral mesogastrium. these include the lesser omentum (hepatogastric ligament, hepatoduodenal ligament) and the ligaments of the liver (falciform ligament, coronary ligaments, right and left triangular ligaments). of the answer choices, only the greater omentum is part of the dorsal mesogastrium.
