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 Holmes and Rahe stress scale was developed as a method of assessing the risk of disease from life changes. [25] The scale lists both positive and negative changes that elicit stress.

The "stress hormone", cortisol, is a glucocorticoid that binds to glucocorticoid receptors. [81] [82] [83] Psychological stress induces the release of cortisol from the adrenal gland by activating the hypothalamic–pituitary–adrenal axis (HPA axis).
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 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.

Chargers running back J.K. Dobbins suffered a knee injury in Week 12 vs. Ravens. Here's what we know on his potential return.
Frequent stress: the magnitude and frequency of response to stress is what determines the level of allostatic load which affects the body. Failed shut-down: the inability of the body to shut off while stress accelerates and levels in the body exceed normal levels, for example, elevated blood pressure.
