HPA Axis Stress Response Cascade

Hypothalamus CRH triggers pituitary ACTH, driving adrenal cortisol; cortisol closes the negative feedback loop.

A free, animated hpa axis stress response cascade you can read here or embed on any website, from Scrollchart.

HPA Axis Stress Response Cascade

CRH from the paraventricular nucleus drives ACTH from anterior pituitary, which drives cortisol from adrenal cortex. Cortisol then exerts negative feedback at both hypothalamus and pituitary, damping further CRH/ACTH output. The diagram makes the closed-loop dynamics legible with a stress-input arrow at the top.

Source & accuracy

This hpa axis stress response cascade is an editorial illustration built to represent the concept accurately. Where it shows figures, they are typical or representative values chosen to make the relationship clear, not a single underlying dataset. The diagram and its explainer are reviewed and maintained centrally, and updated over time as understanding improves.

Following the cascade from brain to adrenal

This diagram emphasizes the HPA axis as a closed loop. The hypothalamus initiates the chain by secreting corticotropin-releasing hormone (CRH). CRH drives the pituitary to release adrenocorticotropic hormone (ACTH), and ACTH stimulates the adrenal cortex to produce cortisol. Each step amplifies the signal as it descends.

The cascade is hierarchical: a small CRH signal can yield a much larger cortisol output, which lets the brain set the gain on the whole stress response from the top.

How cortisol closes its own circuit

The loop closes because cortisol feeds back on the levels above it. Rising cortisol inhibits further CRH release at the hypothalamus and further ACTH release at the pituitary. This negative feedback prevents overshoot and returns the system toward baseline once a stressor resolves.

When feedback is blunted, cortisol can stay elevated, which is part of why feedback testing features in clinical evaluation of the axis. This is general educational information, not medical advice; HPA axis testing should be interpreted by a qualified professional.
