The small intestine forms loops (B2) and slides back into the abdomen (B3) during resolution of the hernia. Meanwhile, the cecum moves from the left to the right side, which represents the additional 180° counterclockwise rotation of the intestine (C, central view). [3] In the process of lengthening growth, the intestinal duct herniates and ...
Intestinal malrotation is a congenital anomaly of rotation of the midgut. It occurs during the first trimester as the fetal gut undergoes a complex series of growth and development. Malrotation can lead to a dangerous complication called volvulus, in which cases emergency surgery is indicated. [1]
As the stomach rotates during early development, the dorsal and ventral mesentery rotate with it; this rotation produces a space anterior to the expanding stomach called the greater sac, and a space posterior to the stomach called the lesser sac.
During the fourth week of development, the stomach rotates. The stomach, originally lying in the midline of the embryo, rotates so that its body is on the left. This rotation also affects the part of the gastrointestinal tube immediately below the stomach, which will go on to become the duodenum.
Later in development, the fetus's body catches up in size relative to the midgut and creates adequate room in the abdominal cavity for the entirety of the midgut to reside. The midgut loops slip back out of the umbilical cord and the physiological hernia ceases to exist.
The human stomach has receptors responsive to sodium glutamate [38] and this information is passed to the lateral hypothalamus and limbic system in the brain as a palatability signal through the vagus nerve. [39] The stomach can also sense, independently of tongue and oral taste receptors, glucose, [40] carbohydrates, [41] proteins, [41] and ...
The asymmetric orientation and position of the gastrointestinal tract arises during development by rotation (see Development of the digestive system). The lateral positions of the digestive organs are on the same side in all vertebrates liver and gall bladder on the right side and the stomach , pancreas , spleen and the final loop of the colon ...
Two of the stages in the development of the digestive tube and its mesentery. The arrow indicates the entrance to the bursa omentalis. The greater omentum develops from the dorsal mesentery that connects the stomach to the posterior abdominal wall. During its development, the stomach undergoes its first 90° rotation along the axis of the ...
