80% of the hormonal secretions epinephrine, and 20% is norepinephrine.
Most Circulating epinephrine arises from the adrenal medulla.
Most Circulating norepinephrine arises from Postganglionic Sympathetic Neurons.
The Adrenal Medulla is not ESSENTIAL FOR LIFE.
Plasma Norepinephrine levels double when one goes from a lying to a standying position.
Exercise, Emergencies, Exposure to cold and Severe Hypoglycemia rapidly increseases Adrenal Medullary Secretion
