1. When Lou described his pain, he indicated that it originated in the epigastric region. Where is the epigastric region and what digestive organs are in this region that Dr. Walker may be considering as the culprit? 2. All of the organs and structures in the epigastric region have a common nerve. What cranial nerve serves this region and which part of the nervous system does it belong to? 3. Inflammation in the alimentary canal will affects the layers of the canal walls. Describe the four basic layers of the alimentary canal, the tissues that make up each layer, and the general function of each layer. 4. Dr. Walker suspects a peptic ulcer, which is confirmed after completing the endoscopy. Describe the signs and symptoms of a peptic ulcer and what the endoscopy would have found to confirm the diagnosis. 5. Lou is curious what H. pylori has to do with an ulcer. Dr. Walker tells him that the H. pylori increases stomach acid secretion and, at the same time, breaks down the lining of your stomach and duodenum. What is the source and normal function of acid in the stomach and what regulates its production? 6. The medication Pepcid that Lou took for partial relief of his dyspepsia is called an H2 (histamine) receptor antagonist, or H2 blocker, meaning its mechanism is to prevent histamine release. What is the normal function of histamine in the stomach? How does blocking histamine fix Lou'e OVer acidity problom?
