Teratoma: from classical greek, meaning ‘monstrous tumour‘.Simply put, a teratoma is an encapsulated tumour which contains tissue or organ components. these tissues may be quite different from the surrounding tissues, and have been known to contain hair, teeth, bone, and on rare occasions more complex organs such as eyes or limbs.There are 2 rare forms of this condition:fetus in fetu and fetiform teratoma.In these cases, the cyst contains tissue components which resemble a malformed foetus. Both may contain partial/complete organ systems, even major body parts such as torso or limbs. However, fetus in fetu differs in that it has an apparent spine and bilateral symmetry.The popular medical interpretation of fetus in fetu is as a congenital complication, whereupon one foetus begins growing within it’s twin. However, without the appropriate in utero conditions, a fetus in fetu cannot develop to physical maturity. There are reported cases of mature teratome which contain partially developed organ systems, cranial bones, and a rudimentary beating heart.A fetus in fetu can be considered alive only in a very limited sense, as it’s blood supply for tissue and organs are provided directly by it’s host. additionally, all cases of fetus in fetu present critical defects, such as no functional brain, heart, lungs, gastrointestinal tract, or urinary tract.

Simply put, a teratoma is an encapsulated tumour which contains tissue or organ components. these tissues may be quite different from the surrounding tissues, and have been known to contain hair, teeth, bone, and on rare occasions more complex organs such as eyes or limbs.

There are 2 rare forms of this condition:

fetus in fetu and fetiform teratoma.

In these cases, the cyst contains tissue components which resemble a malformed foetus. Both may contain partial/complete organ systems, even major body parts such as torso or limbs. However, fetus in fetu differs in that it has an apparent spine and bilateral symmetry.

Chronic Pancreatitis (Ultrasound and CT of One Patient).

Chronic pancreatitis can lead to permanent structural damage of the parenchyma, leading to impaired exocrine and endocrine function. Over time, the pancreas can begin to develop progressive patchy fibrosis that can eventually progress to calcification as seen in the bright white spots on the CT scan.

Endocrine islet cells;
Alpha cells - secrete glucagon which increases blood sugar
Bata cells - secrete insulin which decreases blood sugar
Delta cells - secrete somatastatin, acts as an auto regulator
Gamma cells - VIP cells
G cells - secrete gastrin promote acid
PP cells or F cells - secrete pancreatic polypeptide
Exocrine Acini cells:
enzyme SECRETIONS:
Lipase= breaks down fat
Amylase= breaks down carbs —> sugars
Trypsin= breaks down proteins to amino acids
Elastase= destroy the blood vessels wall (most dangerous)
*HORMONES RELEASED WHEN FOOD ENTERS THE DUODENUM INCLUDE:1) Cholecystokinin (CCK)- released by acini cells, stimulates secretion of pancreatic enzymes2)
Gastrin (controlled by vagal nerve)- stimulates secretion of gastric acids from stomach; stimulates growth of mucosa3)
Secretin- stimulates secretion of bicarbonates; released by duodenal cells; produces panc juice which allows enzymes to travel w/ in ducts
metabolicmeanderings:

The pancreas is a glandular organ that has a head, body, and tail.  The head is closest to the duodenum of the small intestine.  The pancreas has both endocrine and exocrine tissue.   The endocrine areas are composed of islet cells that produce glucagon and insulin.  The exocrine tissue is made up of the acinar glands.  Digestive enzymes are produced by the acini cells of the acinar glands.
