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 ...
A Corticotropin-releasing hormone antagonist (CRH antagonist) is a specific type of receptor antagonist that blocks the receptor sites for corticotropin-releasing hormone, also known as corticotropin-releasing factor (CRF), which synchronizes the behavioral, endocrine, autonomic, and immune responses to stress by controlling the hypothalamic-pituitary-adrenal axis (HPA axis).

Definitions differ, and may be along the lines of continual activation of the stress response, [43] stress that causes an allostatic shift in bodily functions, [5] or just as "prolonged stress". [44] For example, results of one study demonstrated that individuals who reported relationship conflict lasting one month or longer have a greater risk ...
Thus, reproductive function can be altered through psychological or physiological stress through the HPA axis due to the modulatory effects that this pathway has on the HPO axis: its activation, which can occur in states of low energy availability (LEA) as an adaptive response to physical, nutritional, or extreme emotional stress, causes the ...
The ACTH test (also called the cosyntropin, tetracosactide, or Synacthen test) is a medical test usually requested and interpreted by endocrinologists to assess the functioning of the adrenal glands' stress response by measuring the adrenal response to adrenocorticotropic hormone (ACTH; corticotropin) or another corticotropic agent such as tetracosactide (cosyntropin, tetracosactrin; Synacthen ...
The hypothalamus-pituitary-adrenal (HPA) axis is a neuroendocrine system largely involved in ascertaining the levels of cortisol circulating the body at any given point in time. As cortisol plays a key role in the stress response, so does the HPA axis.
NAD supplements are the latest health trend to explode on TikTok, where people claim the supplements can help boost metabolism, improve cognition, and slow or even reverse aging.
First proposed by Peter Sterling and Joseph Eyer in 1988, the concept of allostasis shifts the focus away from the body maintaining a rigid internal set-point, as in homeostasis, to the brain's ability and role to interpret environmental stress and coordinate changes in the body using neurotransmitters, hormones, and other signaling mechanisms.
