Which statement most accurately shows a limitation of nervous control compared with hormonal control?
Answer and explanation
Correct answer: Nervous control directly reaches connected parts through nerve pathways, whereas hormones can travel through blood to distant organs.
Nervous control is rapid and specific because electrical impulses travel along particular neurons and nerve pathways to connected target regions. This pathway-based arrangement limits direct reach to tissues connected with nerves. Hormones, in contrast, are released into the bloodstream and may reach target organs far from the secreting gland, although only cells with suitable receptors respond. Thus option A correctly identifies the limitation; the other statements reverse or exaggerate the properties of the two systems.
