Chapter 18 Part 4 Endocrine Glands Flashcards
What organ has mixed exocrine and endocrine functions
pancreas
What is located inferior to the liver, head in midline, tail extends to LUQ, tail portion is retroperitoneum, and duodenum wraps aroundhead
pancreas
What pancreas cells are digestive
acinar cells
The acinar cells of the pancreas have enzymatic secretions into the intestine lumen via the _____
hepatopancreatic duct
The hepatopancreatic duct leads to the
duodenum
Exocrine parts of the pancread include secreting enzymes
protease
amylase
and lipase
Endocrine hormone secretion from the pancreas secrete
inulin
glucagon
somatostatin
what are small patches of tissue in the pancreas that contain A cells that secrete glucagon and beta cells that secrete insulin
islets and langerhan
What makes up 1-2% of pancreas
Islet of langerhan
alpha cells secrete
glucagon
glucagon does what to BS
increases
Beta cells secrete
insulin
Insulin does what to BS
decreases it
delta cells are somatostatins that
inhibits both insulin and glucagon
Inadequate lack of insulin production by pancreatic beta cells result in
Diabetes Mellitus -type 1
most cases of type -1 are a result of ____-
autoimmune destruction
Insulin dependent with
autoimmune link
What is insulin resistence
DM -type 2
Type 2 DM is a
receptor vs secretion problem
insulin receptors on target cells become —-
insulin resistant
Insulin receptors become incompetent at producing insulin in DM 2 ==
accumulation of glucose in blood
What can casue the development of TYPe 2 diabetes
obesity, low physical activity, diets high in carbs, alcohol, high stress life
What is the least known pineal gland
pineal gland
What gland hangs from roof 3rd ventricle in diencephalon
