Selye concluded that stressors stimulate the release of from the anterior pituitary, which in turn triggers the release of from the adrenal cortex.

Stressors stimulate the release of adrenocorticotropic hormone from anterior pituitary which then stimulates the secretion of cortisol from adrenal cortex.

Explanation:

Stress can be described as the response of an organism to an environmental condition or event or external stimulus which causes stress.

The major systems that respond to stress are autonomic nervous system and hypothalamic-pituitary-adrenal axis (HPA axis).

The HPA axis is responsible for releasing vasopressin and corticotropin releasing hormone from hypothalamus which stimulates the anterior pituitary to secrete adrenocorticotropic hormone. The adrenocorticotropic hormone the stimulates the secretion of cortisol from adrenal cortex of the adrenal gland.
