Exocrine And Endocrine Pancreas

The secretions of the exocrine pancreas provide for digestion of a meal into components that are then available for processing and absorption by the intestinal epithelium. Without the exocrine pancreas, malabsorption and malnutrition result. This chapter describes the cellular participants responsible for the secretion of digestive enzymes and fluid that in combination provide a pancreatic secretion that accomplishes the digestive functions of the gland. Key cellular participants, the acinar cell and the duct cell, are responsible for digestive enzyme and fluid secretion, respectively, of the exocrine pancreas. This chapter describes the neurohumoral pathways that mediate the pancreatic response to a meal as well as details of the cellular mechanisms that are necessary for the organ responses, including protein synthesis and transport and ion transports, and the regulation of these responses by intracellular signaling systems. Examples of pancreatic diseases resulting from dysfunction in cellular mechanisms provide emphasis of the importance of the normal physiologic mechanisms.

Exocrine and Endocrine Pancreas: Clinical Implications - ECAB - E-Book

This innovative teaching atlas provides the reader with a practical approach to the diagnosis and management of the common and uncommon diseases that may involve the pancreatic gland. Its perspective is multidisciplinary, the authors being radiologists, surgeons, pathologists, and gastroenterologists who have worked together for the past 25 years. Very concise descriptions of clinical presentation, pathology, imaging, and management are provided for a great variety of pathologic conditions, and a wealth of illustrative material displays intraoperative appearances, gross specimens, histology, and radiological findings. Pancreatic surgery, including transplantation, is also discussed, and the final chapter presents a gallery of challenging and diverse cases. Specialists and residents in a range of specialties will find this atlas to be an invaluable aid, and it will also serve as an excellent reference for medical students.
