MCAT Question of the Day 200– Psychology

The adrenal gland produces epinephrine and norepinephrine as part of the parasympathetic response to stressful triggers.

At the onset of a stressful event, the adrenal gland triggers a cascade of events in the hypothalamus and pituitary, resulting in activation of the sympathetic nervous system’s “fight or flight” response.

The adrenal medulla produces cortisol, which helps regulate blood pressure and heart rate, in response to stress.

The adrenal medulla produces adrenaline in response to acute stressors and the adrenal cortex produces cortisol in response to longer-term, low-grade stressors.
