Which of the following describes an endocrine control mechanism where a hormone from a target gland rapidly suppresses its upstream regulators (within minutes)?
Show answer and explanation
Correct answer: Fast (non-genomic) negative feedback
Fast (non-genomic) negative feedback — such as rapid feedback inhibition of the HPA axis by cortisol — can suppress upstream hormone release within minutes, independent of gene transcription.
