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 ...
The activation of the HPG axis in both males and females during puberty also causes individuals to acquire secondary sex characteristics. This process, known as gonadarche, is preceded by adrenarche, the maturation of the adrenal glands, which contributes to the production of androgens responsible for some pubertal changes.
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 ...
The HPA axis ultimately results in the release of cortisol, which generally has immunosuppressive effects. However, the effect of stress on the immune system is disputed, and various models have been proposed in an attempt to account for both the supposedly "immunodeficiency" linked diseases and diseases involving hyper activation of the immune ...
In rural areas, “the natural environment helps control the HPA axis, which is our body's main stress response system,” explains Mary Poffenroth, a biopsychologist who investigates how the ...
The activation of SNS during an immune response might be aimed to localize the inflammatory response. The body's primary stress management system is the HPA axis. The HPA axis responds to physical and mental challenge to maintain homeostasis in part by controlling the body's cortisol level.
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).

The hypothalamic–pituitary–somatotropic axis (HPS axis), or hypothalamic–pituitary–somatic axis, also known as the hypothalamic–pituitary–growth axis, is a hypothalamic–pituitary axis which includes the secretion of growth hormone (GH; somatotropin) from the somatotropes of the pituitary gland into the circulation and the subsequent stimulation of insulin-like growth factor 1 ...
