The neuroendocrine system plays a pivotal role in the stress response. The [[hypothalamus]] activates the [[sympathetic nervous system]] and the [[hypothalamic-pituitary-adrenal (HPA) axis]]. The HPA axis involves the release of [[corticotropin-releasing hormone (CRH)]] from the hypothalamus, which stimulates the pituitary gland to secrete [[adrenocorticotropic hormone (ACTH)]]. ACTH then prompts the adrenal cortex to release [[cortisol]], a key stress hormone. | The neuroendocrine system plays a pivotal role in the stress response.
