How does the adrenal gland respond to short and long-term stress?
Short
Hypothalamus activates adrenal medulla via nerve impulses
The nerve impulses cause sympathetic activation
The adrenal medulla secretes adrenaline and noradrenaline (or epinephrine and norepinephrine)
These hormones cause a breakdown of glycogen to glucose, changes in circulation, increase heart rate and
dilate air passages in lungs, increases respiratory rate, dilates pupils….
Long
Hypothalamus releases hormones (CRH) to the anterior pituitary
This stimulates the release of ACTH into the bloodstream.
ACTH stimulates the adrenal cortex to secrete mineralocorticoids and glucocorticoids.
The glucocorticoids stimulate glucose and glycogen synthesis, stimulate release of fatty acids, cause tissues
to break down fatty acids and proteins, immunosuppressive and anti-inflammatory
