Viscera

peritoneum Functions Secretes a lubricating serous fluid that continuously moistens the associated organs Absorb Support viscera

This duodenojejunal flexure is surrounded by a fold of peritoneum containing muscle fibers called the suspensory muscle (ligament) of duodenum (ligament of Treitz).

Stomach

the superior part (first part) extends from the pyloric orifice of the stomach to the neck of the gallbladder, is just to the right of the body of vertebra LI, and passes anteriorly to the bile duct, gastroduodenal artery, portal vein, and inferior vena cava-clinically, the beginning of this part of the duodenum is referred to as the ampulla or duodenal cap, and most duodenal ulcers occur in this part of the duodenum; the descending part (second part) of the duodenum is just to the right of midline and extends from the neck of the gallbladder to the lower border of vertebra LIII-its anterior surface is crossed by the transverse colon, posterior to it is the right kidney, and medial to it is the head of the pancreas-this part of the duodenum contains the major duodenal papilla, which is the common entrance for the bile and pancreatic ducts, and the minor duodenal papilla, which is the entrance for the accessory pancreatic duct, and the junction of the foregut and the midgut just below the major duodenal papilla; the inferior part (third part) of the duodenum is the longest section, crossing the inferior vena cava, the aorta, and the vertebral column (Figs. 4.61B and 4.62)-it is crossed anteriorly by the superior mesenteric artery and vein; the ascending part (fourth part) of the duodenum passes upward on, or to the left of, the aorta to approximately the upper border of vertebra LII and terminates at the duodenojejunal flexure

This duodenojejunal flexure is surrounded by a fold of peritoneum containing muscle fibers called the suspensory muscle (ligament) of duodenum (ligament of Treitz).

The surface projection of the base of the appendix is at the junction of the lateral and middle one-thirds of a line from the anterior superior iliac spine to the umbilicus (McBurney's point). People with appendicular problems may describe pain near this location

Paracolon

1) the myenteric (or Auerbach's) plexus, which is specifically concerned with regulating the musculature of the gut; and (2) the submucus (or Meissner's) plexus, which is located, as the name implies, just beneath the mucus membranes of the gut and is concerned with chemical monitoring and glandular secretion.

Liver

Ant.

Inf. the right anterior part of the stomach; the superior part of the duodenum; the lesser omentum; the gallbladder; the right colic flexure; the right transverse colon; the right kidney; the right suprarenal gland

Post. & sup.

a diaphragmatic surface in the anterior, superior, and posterior directions; a visceral surface in the inferior direction the subphrenic recess separates the diaphragmatic surface of the liver from the diaphragm and is divided into right and left areas by the falciform ligament, a structure derived from the ventral mesentery in the embryo; the hepatorenal recess is a part of the peritoneal cavity on the right side between the liver and the right kidney and right suprarenal gland

Pancreas

to the greater curvature of the stomach by the gastrosplenic ligament, which contains the short gastric and gastro-omental vessels; to the left kidney by the splenorenal ligament (Fig. 4.92), which contains the splenic vessels.

Celiac artery

inferior mesenteric artery
