Stress (biology)

stressenvironmental stressemotional stress
A stressor is a chemical or biological agent, environmental condition, external stimulus or an event that causes stress to an organism.
Stress, either physiological or biological, is an organism's response to a stressor such as an environmental condition.

Adrenal medulla

After which, the adrenal medulla secretes epinephrine.
In response to stressors such as exercise or imminent danger, medullary cells release the catecholamines adrenaline and noradrenaline into the blood.

Chemical stresses also produce biomechanical responses associated with metabolism and tissue repair.

Hypothalamus

hypothalamicanterior hypothalamushypothalamic hormones
One possible mechanism involves stimulation of the hypothalamus, CRF (corticotropin release factor) -> pituitary gland releases ACTH (adrenocorticotropic hormone) -> adrenal cortex secretes various stress hormones (e.g., cortisol) -> stress hormones (30 varieties) travel in the blood stream to relevant organs, e.g., glands, heart, intestines -> flight-or-fight response. Between this flow there is an alternate path that can be taken after the stressor is transferred to the hypothalamus, which leads to the sympathetic nervous system.
