Its located just to the right of the midline in the transpyloric plane (through L1)
What area surrounds the opening of the esophagus to the stomach?
The cardia
What area of the stomach is superior to the cariac orifice?
Fundus
What is the largest region of the stomach?
the body
What two things make up the pyloric part of the stomach?
- Pyloric antrum
- Pyloric canal
What attaches to the greater curvature of the stomach?
- Gastrosplenic ligament
2. greater omentum
What attaches to the lesser curvature of the stomach?
Lesser omentum
What is the arterial blood supply to the stomach?
- Left Gastric Artery (from celiac trunk)
- Right Gastric Artery (from Hepatic a. proper)
- Right Gastro-Omental Artery (from gastroduodenal a.)
- Left Gastro-Omental a. (from splenic a.)
- Posterior Gastric a. (from splenic a.)
In what quadrant of the abdomin is the spleen located in?
Left upper quadrant
T or F: the spleen lies on the diaphragmatic surface deep to ribs 9-11.
True
What connects the spleen to the stomach and what is contained in this structure?
- Gastrosplenic Ligament
Contains:
- Short gastric vessels
- Gastro-omental vessels
Besides the stomach what other structure is the spleen attached to?
- Left kidney via splenorenal ligament
Splenorenal ligament contains:
1. Splenic vessels
What is the arterial supply to the spleen?
Splenic artery from the celiac trunk
What is the entry point for the splenic vessels?
Splenic Hilum
What 3 facets are located on the visceral surface of the spleen?
- Gastric
- Colic
- Renal
In what quadrants is the liver located?
- Right upper quadrant
- a portion of Left upper quadrant
T or F: the diaphragmatic surface of the liver extends into the anterior, superior, and posterior directions
True
What surface of the liver is located in the inferior direction?
Visceral surface
Describe the location and anatomical features of the subphrenic recess.
- separates the diaphragmatic surface of the liver from the diaphragm (located more anteiorly)
- divided into L and R areas by falciform ligament
A portion of what embryologic structure gives rise to the falciform ligament?
- ventral mesentary
T or F: the hepatorenal recess is a part of the peritoneal cavity on the left side between the liver and the Left kidney and Left suprarenal gland
False, its located on the right side between the right kideny and left suprarenal gland
What is the porta hepatis of the liver?
- serves as the point of entry into the liver for:
1. hepatic arteries
2. portal vein - point of exit for:
1. hepatic ducts
What attaches the liver to the anterior abdominal wall?
falciform ligament
What is the only part of the liver not surrounded by visceral peritoneum?
bare area (part that is pressed against the diaphragm)
What are the boundaries of the bare area?
- Anterior: anterior coronary ligament
- Posterior: Posterior coronary ligament
- Laterally: right triangular ligament
What two structures come together laterally to form the right triangular ligament?
Anterior and Posterior Coronary ligaments
What divides the liver into right and left lobes?
Fossae fot the gallbladder and inferior vena cava
T or F: the caudate and quadrate lobes arise from the left lobe of the liver
False, they arise from the right lobe
What are the boundaries of the quadrate lobe?
Left: ligamentum teres
Right: Fossa for gallbladder
-Note: the quadrate lobe is FUNCTIONALLY more related to the left lobe of the liver
T or F: the caudate lobe is visible from the anterior part of the liver
False, the quadrate lobe is visible on the anterior part of the liver
What are the boundaries of the caudate lobe of the liver?
Left: fissure for ligamentum venosum
Right: Groove for the inferior Vena Cava
What provides arterial supply to the liver?
- Right and Left hepatic arteries
both branch from the heaptic artery proper a branch of the common hepatic artery from the celiac trunk
Where is the gallbladder located?
Between the right and quadrate lobes
What is the fundus of the gallbladder?
- rounded end of the gallbladder that projects to the inferior border of the liver
What two structures join to form the common hepatic duct?
R and L hepatic ducts
What two structures join to form the bile duct?
Cystic duct and common hepatic duct
What artery branches from the abdominal aorta at the upper border of L1?
Celiac artery
What artery branches from the abdominal aorta at the lower border of L1?
Superior mesenteric artery
What artery branches from the abdominal aorta at at L3?
Inferior mesenteric a.
What makes up the structures of the foregut and what is the blood supply to this area?
Start: Abdominal esophagus
End: Midway along descending duodenum (including major duodenal papilla)
-BS: Celiac Trunk
What makes up the midgut and what is the blood supply to this area?
Start: Inferior to major duodenal papilla
End: Distal 1/3 of transverse colon
-BS: Superior Mesenteric a.
What makes up the hindgut and what is the blood supply to this area?
Start: Distal 1/3 transverse colon
End: Midway down anal canal
-BS: Inferior Mesenteric a.
