MindMap Gallery Medicine - Supracolonic Region
A mind map about human anatomy: a mind map of the upper colon area, including the liver, stomach, duodenum, pancreas, etc. Hope it helps everyone.

Supracolonic area
liver
It is the largest digestive gland in the human body
Location: Most are located in the right rib area and supragastric area, and a few are located in the left rib area.
Upper border of liver: adjacent to diaphragm
Lower limit of liver: In adults, it is consistent with the costal arch, and in children, it is no more than 2cm below the costal arch.
form
Diaphragm: naked area
Dirty noodles: Yotsuba
left longitudinal ditch
right longitudinal groove
Transverse groove: porta hepatis
blood supply
Enters the liver: proper hepatic artery, hepatic portal vein
Exits the liver: hepatic vein, finally empties into the inferior vena cava
Liver fissures and liver segments
intrahepatic ducts
Glisson system
Left and right halves of the liver, five leaves and six segments
Liver Segments: Graphical Illustration
extrahepatic biliary tract
left and right hepatic ducts
common hepatic duct
gallbladder
common bile duct
Segments: upper duodenum, posterior pancreatic segment and intramural segment
Hepatopancreas ampulla: opens into the duodenal papilla
discharge of bile
The liver secretes bile - left and right hepatic ducts - common hepatic duct - cystic duct - gallbladder (after eating) - cystic duct - common bile duct - duodenal papilla - descending duodenum
Stomach
Form and distribution
couple
cardia
pylorus
Two fates
upper edge of lesser curvature of stomach
Lower edge of greater curvature of stomach
two walls
Front wall: forward and upward
Back wall: toward the back and downwards
four parts
Pylorus
Pyloric sinus
pyloric canal
Prevalent sites for gastric ulcers and gastric cancer
cardiac department
fundus of stomach
gastric body
Location and proximity
Location: Most of them are located in the left rib area, and a small part is located in the upper abdominal area.
front wall of stomach
posterior wall of stomach
Structure (outer longitudinal middle ring inwardly inclined)
mucosal folds
pyloric valve
pyloric sphincter
nerves of stomach
Sympathetic nerves: inhibit gastric motility and gastric acid secretion
Parasympathetic nerve (vagus nerve): Promotes gastric motility and gastric acid secretion
blood supply
arteries of the stomach
left gastric artery
right gastric artery
left gastroepiploic artery
right gastroepiploic artery
short gastric artery
retrogastric artery
gastric veins
Left gastric vein and right gastric vein - empties into hepatic portal vein
Left gastroepiploic vein and short gastric vein - empties into splenic vein
Right gastroepiploic vein – empties into superior mesenteric vein

Pancreas (the second largest digestive gland in the human body)
location and proximity
Anterior: The septal sac is in contact with the stomach
Posteriorly: inferior vena cava, hepatic portal vein, common bile duct, abdominal aorta
Right end: Surrounded by the duodenum
Left end: Arrive at the splenic hilum
