1. Describe the boundaries of the abdomen. Describe the topographic lines and other surface features that are used to define the various quadrants and regions of the abdomen. 2. Name the alimentary organs that comprise the foregut, midgut and hindgut, and name the arteries whose blood supplies define these gut regions. 3. Describe the peritoneal linings of the abdomen. List the differences (e.g., relative volumes, contents) between the abdominal and peritoneal cavities. 4. Describe the various "ligaments" found within the abdominal cavity and name the organs and structures to which they are attached. Explain why how those “ligaments” differ from the ligaments described in the musculoskeletal systems. 5. Name the two spaces (and subdivisions of each of these spaces) within the peritoneal cavity. Describe the location of the "window" that interconnects the two spaces of the peritoneal cavity. 6. Describe the anatomy, blood supply, lymphatic drainage, sensory innervation, and autonomic innervation for the following abdominal organs:

abdominal esophagus ascending colon

cecum

descending colon duodenum (first part) duodenum (fourth part) duodenum (second part) duodenum (third part) gallbladder ileum

jejunum

transverse colon vermiform appendix 7. Describe the anatomy of the biliary and pancreatic ductal systems, and describe some common variations that are observed.

8. Describe the anatomy and functional significance of the porta hepatis and the

9. Describe the anatomy of the following arteries. State whether these arteries are paired or unpaired, where they emerge off the aorta, what their significant branches are, and what visceral organs, if any, receive their blood (recall that some of the arteries listed below subserves one of the walls of the abdominal cavity). hepatic portal venous system. Name the four areas of the body where varices (i.e., large, engorged veins) commonly form as secondary effects of hepatic portal venous hypertension. celiac trunk
