    • Electrical
    • Synaptic
    • Hormonal
    • Reflex
  10. How are hormones transported from endocrine glands to their target organs?

    • Through the lymph
    • In the bloodstream
    • Across cell synapses
    • Along nerve cells
  11. Does the pituitary gland act on other glands to release hormones?

    • Only during sleep
    • Yes
    • No
    • Only in plants
  12. What type of organ is the target of a pituitary hormone?

    • A sensory nerve cell

    • Thyroid
    • Pituitary gland
    • Pancreas
    • Adrenal gland
  16. What is the route by which hormones travel from a gland to a target organ?

    • Bloodstream
    • Spinal cord
    • Duct
    • Neurone

    • Thyroid gland
    • Adrenal gland
    • Pituitary gland
    • Pancreas
  18. Why are hormonal responses generally slower than nervous responses?

    • Moved by diffusion
    • Travel via synapses
    • Transported by blood
    • Carried down axons
  19. What is the primary destination of hormones released into the bloodstream?

    • Target organ
    • Synapse
    • Nerve pathway
    • Spinal cord
  20. Why do hormonal responses last longer than nervous responses?

    • Glands produce more energy
    • Electrical impulses travel fast
