Types of Pancreas Tumors Cancer of the pancreas is not one disease As many as ten different tumor types have been lumped under the umbrella term "cancer of the pancreas", classified as exocrine or endocrine tumorsEach of these tumors has a different appearance when examined with a microscope, some require different treatments, and each carries its own unique prognosis Everything can look strange under a microscope, even the human body Below we have put together a list of images of different parts of the human body under the microscope Some have been increased up to 5,000 times!The pancreas contains tissue with an endocrine and exocrine role, and this division is also visible when the pancreas is viewed under a microscope The majority of pancreatic tissue has a digestive role The cells with this role form clusters (Latin acini) around small ducts, and are arranged in lobes that have thin fibrous walls

The exocrine portion of the pancreas consists of the pancreatic acini and their ducts The basophilic basal and eosinophilic apical regions seen under the Light microscopic studies of the living acinar pancreas, although limited in number, have revealed valuable information concerning dynamic aspects of microvascular and parenchymal structure and function For example, it has been found that 1) the living organ in anesthetized animals can be imaged with a resolution approaching the limit of the light microscope;In the mouse exocrine pancreas cell under the light microscope They are never found in tissue from animals injected with distilled water Although their detailed structure, as seen with the electron microscope, is so varied, they closely resemble the inclusions identified as neutral red granules in earlier work (Byrne, in press)

 The pancreas is both an exocrine accessory digestive organ and a hormone secreting endocrine gland The bulk of the pancreatic tissue is formed by the exocrine component, which consists of many serous pancreatic acini cells These acini synthesize and secrete a variety of enzymes essential to successfully "rest and digest"Within the pancreas, these two functions are performed by different tissues, which can be clearly seen and distinguished from each other when observed under a microscope Most of the cells of the pancreas secrete digestive enzymes (exocrine function) but throughout the organ, there are small sections of cells known as the islets of Langerhans that produce hormones (endocrineExocrine the vast majority of tumors of the pancreas arise in the exocrine part and these cancers look like pancreatic ducts under the microscope These tumors are therefore called "ductal adenocarcinomas," or simply "adenocarcinoma," or even more simply " pancreatic cancer "

Pancreatic Insufficiency & Exocrine Pancreas Dysfunction During a consult when there is a problem with digestion I mentally follow a piece of food from the mouth down the digestive tract to the other end and muscle test each anatomical feature as the food passes Wherever the energy is blocked, my fingers will release letting me know what part of the digestive tract needs work The endocrine pancreas as it is seen under the microscope The endocrine islets are distributed between the exocrine pancreatic tissue and can have a spherical to ovoid, or strungout, form The threadlike arrangement of the epithelial cells and the dense meshwork of capillaries are apparentThis page has endocrine histology of the pancreas under high powerThe pancreas is a mixed gland meaning it has both endocrine and exocrine tissue When look at the pancreas under the microscope you will see numerous pancreatic acini cells that

The architecture of pancreas from organ donors was studied by light and scanning electron microscopy and by wax reconstruction of serial sections It is concluded that the zymogen granulecontaining cells of normal human exocrine pancreas are ar­ ranged as branching tubules that vary in diameter and curve acutelyBackground During the process of islet isolation, pancreatic enzymes are activated and released, adversely affecting islet survival and function We hypothesize that the exocrine component of pancreases harvested from preweaned juvenile pigs is immature and hence pancreatic tissue from these donors is protected from injury during isolation and prolonged tissue cultureThe pancreas of insulinrequiring diabetics becomes progressively less capable of responding to the stimuli used for testing exocrine pancreatic function Frier, Saunders, Wormsley and Bouchier, 1976 and post mortem the whole gland is found to be shrunken and fibrosed Vertiainen, 1944 Furthermore the exocrine cells closest to the islets
