The second axis that comprises the stress response stage is the neuroendocrine (fight or flight) axis, which causes intermediate stress effects (Everly & Lating 2013). First, the body engages in a fight or flight response in the presence of a perceived threat, and the primary organ involved in this is process is the adrenal medulla (Everly & Lating, 2013). Next, at the time of this publication, researchers had identified that the dorsomedial amygdlar complex as the utmost point for which the fight or flight response occurred (Everly & Lating, 2013). Originating there, neural impulses subsequently travel to the hypothalamic region, then the thoracic spinal cord, convene at the celiac ganglion, and then inhibit the adrenal medulla (Everly & Lating, 2013). Subsequently, the authors illustrated that the chomaffin cells that comprise the adrenal medulla create and then discharge adrenal medullary catecholamines (Everly & Lating, 2013). Two hormones, norepinephrine and epinephrine, comprise the adrenal medullary catecholamines (Everly & Lating, 2013). Therefore, when stimulated, the adrenal medulla will release its catecholamines, which have a slower, but similar effect to a direct sympathetic innervation (Everly & Lating, 2013). Furthermore, activation of this axis in response to a stressor has been shown to have somatic effects on humans and overlap with the final stress-response axis (Everly & Lating, 2013).
The final stress-response axis is the endocrine axes, which is…
