running within) and is a point of firm attachment to the dorsal body wall, however the small intestines are still relatively mobile. The root of the mesentery is at the center of these mesenteries (and has the cranial mesenteric a. The mesoduodenum, mesojejunum, mesoileum, and mesocolon are mesenteries wrapping the duodenum, jejunum, ileum, and colon, respectively.

The greater and lesser omentum are connective tissues associated with the greater and lesser curvatures of the stomach.

Connecting peritoneum connects the parietal and visceral layers, or the visceral layers of adjacent organs and can form peritoneal folds called ‘mesenteries’, ‘omenta’, or ‘ligaments.’.

The parietal peritoneum is the serous membrane lining the body wall, while the visceral peritoneum is directly on the surfaces of all of the abdominal organs.

The abdominal cavity is formed by the muscles of the abdominal wall, the ribs, and the diaphragm it is lined by peritoneum, which encloses the peritoneal cavity.

extending from the tuber coxae to the costal arch. It is a triangular depression bounded by lumbar transverse processes and the epaxial muscle dorsal to the processes, the last rib, and an oblique muscular thickening of the internal abdominal oblique m.

The paralumbar fossa (ID in bov, but also in eq) is the most common surgical site for entry into the ruminant abdomen.

The subiliac lymph nodes (bov) / subiliac lymphocenter (eq) are found at the cranial edge of the thigh muscles, about midway between the tuber coxae and the fold of the flank.
