Answer:
True
Explanation:
Catecholamines refer to the hormones produced by the adrenal gland present on the upper side of the kidney.
The catecholamine hormone includes the epinephrine, norepinephrine and the dopamine.
During stress conditions, the sympathetic division of the autonomic nervous system gets activated which leads to the release of the norepinephrine from the postganglionic neurons and the prolonged-release leads to the release of the adrenaline from the adrenal glands.
Thus, true is the correct answer.
