Exam 1 Flashcards
List the major functions of the liver
1) Detoxification of blood 2) Storage of glycogen 3) Secretion of bile 4) Protein Synthesis: Blood proteins including clotting factors
Describe the four major parts of the pancreas
- Head
- Lies in curvature of duodenum and anterior to inferior vena cava
- Transversed by common bile duct
- Neck
- Supreior mesenteric artery crosses the neck posteriorly and constrics it
- Tail
- Ends at the hilus of spleen
- Body
- Triagular in cross section and extends across midline across aorta and left renal veins
- Anterior surface lies in floor of omental bursa and is covered by peritoneumm
- Posterior Surface is free from the peritoneum
- Contacts with: Aorta, Superior mesenteric aretry, left kidney, left suprarenal gland
Describe the location of the liver in relation to abdominal quadrants and regions
1) Lies mostly in upper right portion of abdominal cavity -Abdominal regions 1) Right and Left Hypochondriac 2)Epigastric
List the four major parts of the pancreas.
- Head
- Neck
- Tail
- Body
Describe the ligaments and omentum that relate to the omental bursa.
1) Gastrosplenic Ligament 2) Greater Omentum
Define Mesentaries
Double membrane connecting the parietal and visceral peritoneum
Describe the lobes of the liver and the landmarks related to the lobular arrangement of the liver
1) Right = Largest 2) Left = Smaller than right but larger than caudate and quadrate 3) Caudate = Posterior to quadrate and separated from left lobe by lesser omentum -Seperated from right lobe by porta hepatis and inferior vena cava 4)Quadrate = Anterior to caudate lobe
List the ligaments associated with the greater omentum
1) Gastric Ligament 2) Gastrophrenic Ligament 3) Gastrocolic Ligament
What is the Ligamentum Teres?
1) Remnant of the left umbilical vein 2) Round ligament of liver
Describe the Common Hepatic Duct
1) Formed by the union of right and left hepatic ducts of liver 2) Accompanied by portal vein and proper hepatic artery
Examples of coelom
1) Pericardial Cavity 2) Pleural Cavity 3) Abdominapelvic Cavity
What is the Biliary System?
Consists of: 1)Liver 2)Gall Bladder 3) Bile Ducts
What does the gastrosplenic ligament contain?
- Left gastroepiploic artery and vein
- Short Gastric arteries and veins
Describe the Portal Triad
1) Hepatic portal vein (Posterior) 2) Common Hepatic Artery (Anterior and Left) 3) Common Hepatic Duct (Anterior and Right)
Describe the omental bursa
Hollow space that is formed by the greater and lesser omentum and its adj. organs
Describe a peritoneum
Mesodermal membrane that is associated with a true coelom. -Defined as serous membranes -Parietal membrane - which lines the walls of the coelom -Visceral membranes - which covers the viscera within the coelom
List in order the major anatomical subdivisions of the stomach
Cardiac Fundus Body Pylorus
What membrane is associated with a coelom?
Peritoneum
Describe the projections of the liver onto the anterior abdominal wall
1) Projects superiority to xiphisternal junction 2) Projects left as far as apex of heart 3) Projects inferiority to midpoint between xiphoid process and umbilicus
Describe the Coronary Ligament.
1) Anterior Layer: -Formed by reflection of peritoneum from the upper margin of bare area of liver to the under surface of the diaphragm -Continuous with the right layer of the falciform ligament 2) Posterior layer -Reflected from the lower margin of the bare area -Continuous with the right layer of the lesser omentum
List the surfaces and recesses of the liver
1) Surfaces - Diaphragmatic (Anterior, superior, some inferior) - Bare Area - Visceral (Posterioinferior) 2) Recesses -Subphrenic Recess -Heptaorenal Recess
Describe the Falciform Ligament
1) Attaches liver to anterior abdominal wall and to inferior surface of diaphragm 2) Runs to umbilicus
Describe the Pancreatic Duct System
- Main Pancratic Duct: Begins at the head, runs through the panceras parenchyma and exits the gland at the head.
- Turns inferiorly to meet the bile duct
- Hepatopancreatic Ampulla: Junction of main pancreatic duct and common bile duct
- Empties into duodenum via major duodenal papilla
- Accessory Pancreatic Duct: Drains unicate process and inferior head of pancreas
- Empties into duodenum via minor duodenal papilla
Describe the curvatures of the stomach
1) Greater Curvature -> Long convex border of stomach related to greater omentum 2) Lesser Curvature -> Short concave border of stomach related to lesser omentum
Define Portal System
Venous connection between two organs other than the heart -Vein connecting two capillary beds
Which ligament associated with the live contains the ligamentum trees hepatis?
Falciform Ligament
Describe Triangular Ligament
1) Represents double folds of coronary ligaments *** Formed by posterior and anterior coronary ligaments
Define Retroperitoneal
Refers to structures that lie behind the peritoneum -Example: Kidney
Discuss the anatomical positions and describe the major anatomical features associated with the four major parts of the duodenum
- Superior: First distal to pylorus
- Descending Part: Major duodenal papilla and minor duodenal papilla
- Major duodenal papilla empties hepatopancreatic ampulla into duodenum
- Sphincter or oddi controls emptying of common bile duct
- Minor duodenal papilla empties accessory pancreatic duct into duodenum
- Major duodenal papilla empties hepatopancreatic ampulla into duodenum
- Horizontal : Travels to the left
- Acending Part: Meets with jejunum at duodenojejunal junction
Define Rugae
Internal longitudinal ridges that allow expansion of stomach
What is the function of the Cystic duct?
Connects (Common) hepatic duct to gall bladder
List the ligaments associated with the liver
1) Falciform Ligament 2) Coronary Ligament 3) Triangular Ligament
