  1. By Dr. Istvan, Moore, and Howze The Pancreas

  2. General Information The Pancreas is located superior to the Duodenum, and Inferior to the Stomach. The Pancreas is a gland that helps to digest food, as well as regulate blood sugar levels. http://www.medterms.com/script/main/art.asp?articlekey=4743

  3. Pancreas Gland The Pancreas is located below the liver and stomach, and just above the small intestines. It is next to the gall bladder, with bile ducts surrounding it. Its location is key, as it is used in digestion. http://take2designs.com/alcoholsitev2/images/normal_pancreas.jpg

  4. Structure of the Pancreas The Pancreas is separated into two distinct lobes. Glands of the pancreas can release hormones directly into the duodenum or the blood stream. 1: Head of pancreas2: Uncinate process of pancreas3: Pancreatic notch4: Body of pancreas5: Anterior surface of pancreas6: Inferior surface of pancreas7: Superior margin of pancreas8: Anterior margin of pancreas9: Inferior margin of pancreas10: Omental tuber11: Tail of pancreas12: Duodenum

  5. Pancreatic Hormones The Pancreas releases three main hormones: Insulin, Glucagon, and Somatostatin. There is another polypeptide, but its function is unknown. Insulin is made by Beta cells Glucagon is made by Alpha cells Somatostatin is made by Delta cells Unknown polypeptide is made by Gamma cells

  6. Insulin Small protein made of 51 amino acids Beta cells have chemo-receptors that detect blood glucose levels, and secrete insulin in response. Insulin also reduces appetite by affecting cells in the hypothalamus Stimulates adipose tissue to create fat http://dolly.biochem.arizona.edu/Bioc462b_Honors_Spring_2009/abhik/Images/Insulin.jpg

  7. Glucagon A polypeptide of 29 Amino acids Stimulates the liver to release sugar into bloodstream Also acts upon fat tissue to release glucose Has the opposite effect as insulin Blood Glucose Levels http://www.vivo.colostate.edu/hbooks/pathphys/endocrine/pancreas/glucagon_efx.gif

  8. Somatostatin Consists of two polypeptides, with a total of 42 amino acids Works inside the Duodenum to reduce appetite Slows the rate if which the nutrients are absorbed by the small intestines http://www.abcam.com/ps/datasheet/images/ab2366_1.jpg

  9. Diabetes Type 1 diabetes is insulin dependent Daily injections or inhalations are required to keep blood sugar levels in check Most common in children and young adults Caused by autoimmune attack of Beta cells http://biomed.brown.edu/Courses/BI108/BI108_2002_Groups/pancstems/stemcell/pancreas.gif

  10. Diabetes Type 2 diabetes is characterized by irregular blood sugar levels It is fairly easily treated with oral drugs taken daily It is most commonly found in adults, especially those that are overweight http://www.babble.com/CS/blogs/strollerderby/2009/02/diabetes_0.jpg

  11. Diabetes Symptoms Frequent urination Loss of circulation Excessive thirst Rapid weight change Irritability Fatigue Blurred Vision Sweet urine http://www.laughparty.com/funny-pictures/Thirsty-Dog-1007.jpg

  12. Pancreatic Cancer Pancreatic cancer affects roughly 42,000 people every year in the US. About 7,000 of those people survive to live long healthy lives. MRI of abdomen, showing Pancreatic Carcinoma http://www.hpblondon.com/02_pancreas/02_3_p_cancer/files/page14_2.jpg

  13. Pancreatic Cancer Pancreatic Cancer is responsible for more than 50,000 deaths per year. Symptoms include : - Clay colored stool - Abdominal Pain - Indigestion - Diarrhea - Loss of appetite - Nausea - Jaundice

  14. Pancreatic Cancer There are several treatment options Usually pancreatic carcinoma is treated using surgery and chemotherapy. New advancements in cancer treatment allow laser and gamma knife options. Future treatment options are always being developed, including viral treatments.
