The greater omentum (also the great omentum, omentum majus, gastrocolic omentum, epiploon, or, especially in non-human animals, caul) is a large apron-like fold of visceral peritoneum that hangs down from the stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and doubles back to ascend to the ...
In anatomy, the abdominal wall represents the boundaries of the abdominal cavity.The abdominal wall is split into the anterolateral and posterior walls. [1]There is a common set of layers covering and forming all the walls: the deepest being the visceral peritoneum, which covers many of the abdominal organs (most of the large and small intestines, for example), and the parietal peritoneum ...

As the appendix becomes more swollen and inflamed, it begins to irritate the adjoining abdominal wall. This leads the pain to localize at the right lower quadrant.

Percutaneous endoscopic gastrostomy (PEG) is an endoscopic medical procedure in which a tube (PEG tube) is passed into a patient's stomach through the abdominal wall, most commonly to provide a means of feeding when oral intake is not adequate (for example, because of dysphagia or sedation). This provides enteral nutrition (making use of the ...
Diverticulitis, also called colonic diverticulitis, is a gastrointestinal disease characterized by inflammation of abnormal pouches— diverticula —that can develop in the wall of the large intestine. [1] Symptoms typically include lower abdominal pain of sudden onset, but the onset may also occur over a few days. [1]
Carnett's sign. In medicine, Carnett's sign is a finding on clinical examination in which (acute) abdominal pain remains unchanged or increases when the muscles of the abdominal wall are tensed. [1][2] For this part of the abdominal examination, the patient can be asked to lift the head and shoulders from the examination table to tense the ...
