4 steps. Step 1: 'NEGATIVE FEEDBACK - Most hormones are regulated by negative feedback. Rising hormone levels INHIBIT further release. Like a thermostat: when room reaches target temp, heating turns OFF. Example: thyroid axis: Hypothalamus→TRH→Pituitary→TSH→Thyroid→T3/T4. High T3/T4 inhibits hypotha
