What is Pyloroduodenal Junction?

Pyloroduodenal Junction. • Mucosa – It consists of branched, tubular. mucus secreting pyloric glands, which play an important role in the protection of the parts close to the stomach that might be damaged by the stomach acids. These glands are similar to the Brunner’s glands of the duodenum.

What are the defining features in the gastro duodenal region?

A characteristic feature of the duodenum is the Brunner’s glands embedded in the submucosa. These produce – amongst others – mucous secret containing bicarbonate which serves to neutralize the gastric acid. Furthermore crypts of Lieberkuhn lie between the villi. Paneth cells are found in the lumen of these crypts.

Where does the gastroduodenal vein drain blood from?

In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen. It supplies blood directly to the pylorus (distal part of the stomach) and proximal part of the duodenum. It also indirectly supplies the pancreatic head (via the anterior and posterior superior pancreaticoduodenal arteries).

Where is the pyloric sphincter located?

The pyloric sphincter is located where the pylorus meets the duodenum.

Where is the normal location of the spleen?

The normal position of the spleen is within the peritoneal cavity in the left upper quadrant of the abdominal cavity adjacent to ribs nine through 12, just beneath the left diaphragm. The spleen lies behind and to the left side of your stomach (see Figure 1).

Where is the gastroesophageal junction located in the stomach?

In normal esophageal anatomy the gastroesophageal junction (GEJ) is located below the hiatal orifice. It is held in place by both the phrenoesophageal ligaments and an aggregate of posterior attachments between the GEJ and cardia of the stomach.

Where are the spleen, pancreas and gall bladder located?

The spleen, pancreas and gall bladder. The spleen is a non-vital organ located in the left upper quadrant of the abdominopelvic region.

Where does the gastroduodenal artery meet the hepatic artery?

The gastroduodenal artery is a terminal branch of the common hepatic artery along with the proper hepatic artery. It passes inferiorly behind the first part of the duodenum to the left of the common bile duct where it gives off the supraduodenal artery. More inferiorly it bifurcates into 2 arteries at the upper border of the pancreas:
