Fight-or-flight reaction cause activation of:

the adrenal medulla, leading to increased secretion of epinephrine and norepinephrene

the parathyroid glands, leading to increased metabolic rate.

the kidney, leading to suppression of renin angiotensin-aldosterone pathway.

the pancreas leading to a reduction in the blood sugar levels.

The posterior pituitary gland is not a 'true' endocrine gland because

It only stores and releases hormones

It is under the regulation of hypothalamus pressure pulling at the lung walls.
