The fight-or-flight response
A diagrammatic representation of the fight-or-flight response.
A diagrammatic representation of the fight or flight response. Upon sensing a threat the brain stimulates the hypothalamus to secrete corticotropin-releasing hormone that induces adrenocorticotropic hormone from the pituitary to stimulate the release of cortisol from the adrenal cortex to increase blood sugar levels in preparation for fight or flight. The stress response halts or slows down various processes, such as sexual responses and digestive systems, to focus on the stressor situation.
