Why can hormonal control be more suitable than nervous control for long-term growth and metabolism?
Answer and explanation
Correct answer: Hormones can affect target organs slowly and for longer through the blood
The governing concept is the difference between nervous and hormonal coordination. Nerve impulses are excellent for rapid, precise, short-lived actions, whereas hormones travel through blood and may act more gradually but persist for longer, depending on the hormone and target tissue. Sustained regulation of growth and metabolism therefore often benefits from endocrine control. Hormones do reach target organs and are not confined to synapses, so option A is correct.
