Answer:
Epinephrine is a hormone that is released by the adrenal medulla. It's also known as adrenaline as well.
When a patient has overactivity of the adrenal medulla, they will have an epinephrine level of 450pg/dl.
It has many roles in the body including increasing heart rate, blood pressure, and dilating airways. These are all necessary for the fight-or-flight response or to act under stress.
A patient with overactivity of the adrenal medulla would have an abnormal epinephrine level that is too high. The normal range of epinephrine in humans is from 0 to 450 pg/dl.
Explanation:
The adrenal medulla is the middle part of the adrenal gland that is placed on the kidneys on either side of the body. It releases epinephrine into the bloodstream in acute stress conditions to boost up the body’s mechanisms. In pheochromocytoma, there is increased adrenal hormone secretion. It is a tumor of the adrenal gland that oversecrete adrenal hormones. Thus the epinephrine levels of the patient will be above normal levels and the patient must show palpitation, increased sweating, and increased blood pressure as this hormone directly acts on blood vessels and on the heart.
