Lecture 1 (Abdominal Cavity I) Flashcards
What are the muscles of the posterior abdominal wall?
Psoas minor, psoas major, quadratus lumborum, iliacus
A body cavity lined with mesoderm
Coelom
Membranes associated with the coelom
Peritoneum, parietal, visceral
Reference to structures that lie behind the peritoneum
Retroperitoneal (example = kidney)
Double membranes, connect the parietal and visceral peritoneum, functions to support viscera and provide a pathway for blood vessels and nerve to reach viscera
Mesenteries
Ligament, double layer of peritoneum, attaches to liver to the anterior abdominal wall and to the inferior surface of the diaphragm
Falciform ligament
Whar are the major functions of the liver?
Detoxification of the blood, storage of glycogen, secretion of bile, protein synthesis.
Where is the liver located relative to abdominal quadants and regions?
Right hypochondriac (1), left hypochondriac (2), epigastric (3)
Where does the liver project superiorly onto the anterior abdominal wall?
Via xiphisternal junction
Where does the liver project left onto the anterior abdominal wall?
A far as apex of the heart
Where does the liver project inferiorly onto the anterior abdominal wall?
Midpoint between xiphoid process and umbilicus
What ligaments are assocaited with the liver?
Coronary, left triangular, falciform, and round
What mesenteries are associated with the liver?
Ligamentum venosum and lesser omentum
What are the surfaces of the liver?
Diaphragmatic, bare area, visceral
What are the recesses of the liver?
Subphrenic and hepatorenal
Entry point for portal triad.
Portal hepatis
What is transmited through the porta hepatis?
R/L hepatic ducts, R/L hepatic arteries, R/L branches of protal vein, and autonomic plexus and lymphatics
List the lobes of the liver.
R/L lobes, caudate, and quadrate
Venous connection between two organs other than the heart, vein connecting two capillary beds (i.e. hepatic, hypophyseal, renal [not in mammals]).
Portal system
List the ducts associated with the biliary system.
R/L hepatic, common
Components of the bilary system.
Gallbladder, common hepatic duct, cystic duct, common bile duct
Where is the stomach related to the abdominal regions?
Left hypochondriac (2) and epigastric (3)
List in order the anatomical subdivisions of the stomach.
Fundus, body, pylorus
Omenta related to the stomach.
Greater (i.e. connects greater curve to posterior abdominal wall) and lesser (i.e. connects lesser curvature to the liver)
Internal longitudinal ridges of the stomach, permit the expansion of the stomach
Rugae
Protrusion of stomach through the esophageal hiatus in the diaphragm
Hiatal hernia
Arterial supply to the stomach.
L/R gastric a., L/R gastroepiploic a., , and short gastric a.
