Endocrine feedback
Endocrine systems use circulating hormones and receptor-mediated responses to coordinate metabolism, growth, reproduction and stress adaptation.

Signal production
Endocrine cells secrete hormones into circulation; local concentration, receptor expression and clearance determine response.
Axis organization
Hypothalamic releasing signals can regulate pituitary trophic hormones, which stimulate peripheral glands.
Negative feedback
Peripheral hormones commonly inhibit hypothalamic and pituitary output, stabilizing the axis around physiological requirements.
Pulsatility and binding
Circadian rhythms, binding proteins, pregnancy, drugs and illness affect circulating hormone results and how they are interpreted.
