Essay Questions

Pancreatic cancer has a poor prognosis. Discuss the relationships of the pancreas to surrounding structures that may be impacted by pancreatic cancer. (10 pts.)
Much of the organization of the alimentary canal is summarized by the arterial supply. For the foregut, cite the aortic branch providing arterial blood; cite the site of preganglionic sympathetic cell bodies; cite the site of postganglionic sympathetic cell bodies; cite the site of preganglionic parasympathetic cell bodies, cite the site of postganglionic parasympathetic cell bodies; cite the periarterial plexus conveying both sympathetic and parasympathetic pathways to the target viscera; cite the central nodes that convey lymphatic drainage; cite the dermatomes that may be impacted by referred pain. Cite the arterial anastomoses that mark the transition of vascular, autonomic, and lymphatic supply from the foregut to the midgut.
