Question

From the list below, click on all of the actions mediated by the sympathetic nervous system, including epinephrine secreted by the adrenal medulla, during stress. Decreased retention of water and Nat within the body via increased urine output Increased uptake and storage of glucose (glycogenesis) to stock up on an energy supply for later use Diversion of blood from viscera to skeletal muscles by means of vasoconstriction in the former beds and vasodilation in the latter Increased blood flow to abdominal organs by vasodilating blood vessels leading to the stomach and small intestine in order to maximize absorption of important nutrients Increased cardiac function such as elevated heart rate Increased hepatic and muscle glycogenolysis to provide a quick source of glucose Increased lung ventilation by stimulating brain breathing centers and dilating airways Increased breakdown of adipose tissue triglyceride to provide a supply of glycerol for gluconeogenesis and fatty acids for oxidation

Answer 1

Answer:

The actions mediated by the sympathetic nervous system including epinephrine secreted by the adrenal medulla during stress includes

* Diversion of blood from viscera to skeletal muscles by means of vasoconstriction in the former beds and vasodilation in the latter.

* Increased cardiac function such as elevated heart rate

* Increased hepatic and muscle glycogenolysis to provide a quick source of glucose

* Increased lung ventilation by stimulating brain breathing centres and dilating

Airways

* Increased breakdown of adipose tissue to triglycerides to provide supply for glycerol for gluconeogenesis and fatty acids for oxidation.
