Can You Explain The Relationship Between Catecholamines And Metanephrines
Phenol vs ether: The chemical structure of epinephrine, the natural hormone generated in excess by a pheochromocytoma tumor, has an aromatic carbon ring with two adjacent -oh (phenol) groups and a side-chain amino group. Compounds with this structure are called catecholamines. Metanephrine is a metabolite of this hormone, with one phenol converted to an ether (-och3). If elevated, it implies the tumor. ...Read moreSee 1 more doctor answer
Metanephrins are metabolic products of cathecolamines: epinephrin and norepinephrin and can be used to diagnose excess production of these adrenal/sympathetic hormones. They can be measured in blood and urine and are very elevated in a condition called pheochromocytoma which is a tumor found mostly in the adrenal glands ...Read more

Complex: Hi. The relationship between Insulin resistance (IR) and hepatic glucose output (HGO) is complex, an results from IR at the liver (so that Insulin doesn't suppress HGO like it should) as well as unregulated hyper-secretion of glucagon (which inappropriately stimulates HGO even in the face of high blood sugar). The liver's a little storage tank for glucose and a factory for making more! ...Read more

Several kinds: 1st degree-conduction through the av node is >20 ms. 2nd degree type 1, av conduction lengths till a beat is dropped. 2nd degree type 2: beats drop randomly. 3rd degree:there is complete block between the atrial and the ventricles. Bundle branch block: a pathway below the av node (in the ventricles) is blocked - can be right or left. The left has 2 fasicles. ...Read more
Can you please tell me about the 2 major hormones of the pancreas help to regulate blood glucose levels?
Glucagon & insulin: Glucagon increases blood sugars by mobilizing sugars stored in the liver... It's actions are the opposite of insulin's, which reduces blood sugars by facilitating storage of glucose in tissues including the liver. The pancreas also makes enzymes that are important for the digestion of fats. ...Read more
