Schematic of the HPA axis (CRH, corticotropin-releasing hormone; ACTH, adrenocorticotropic hormone) Hypothalamus, pituitary gland, and adrenal cortex The hypothalamic–pituitary–adrenal axis (HPA axis or HTPA axis) is a complex set of direct influences and feedback interactions among three components: the hypothalamus (a part of the brain located below the thalamus), the pituitary gland (a ...
This is significant because glucocorticoid is a regulator of the hypothalamus-pituitary-adrenal axis (HPA) and is known to affect stress response. These stress-related epigenetic changes were accompanied by other characteristics that indicated higher stress and anxiety in these offspring, including increased symptoms of PTSD, greater risk of ...
They can be classified as a hypothalamic–pituitary axis (HP axis) of which the adrenal (HPA Tooltip hypothalamic–pituitary–adrenal axis), gonadal (HPG Tooltip hypothalamic–pituitary–gonadal axis), thyroid (HPT Tooltip hypothalamic–pituitary–thyroid axis), somatotropic (HPS Tooltip hypothalamic–pituitary–somatotropic axis), and ...
Its main function is the stimulation of the pituitary synthesis of adrenocorticotropic hormone (ACTH), as part of the hypothalamic–pituitary–adrenal axis (HPA axis). Corticotropin-releasing hormone (CRH) is a 41-amino acid peptide derived from a 196-amino acid preprohormone.
Glucocorticoids also are in effect during times of stress for the sympathoadrenal system, but provide an inhibitory function for the protection of the body from its own immune system. The glucocorticoids work to inhibit reactions produced from the immune system during times of stress that could cause damage within the body. [4]
HPA axis diagram In the hypothalamic-pituitary-adrenal axis (HPA axis), corticotropin-releasing factor (CRF) is secreted by the hypothalamus in response to stress and other normal body processes. CRH then acts on the anterior pituitary and causes it to secrete adrenocorticotropic hormone (ACTH).

Diagram of the hypothalamic–pituitary–adrenal axis. The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. [1] [2] Stimuli, like stress, improved memory when it was related to learning the subject. [3]
