Question

Which of the following has neurotransmitters as their effector cells?

• A. Nerves
• B. Muscles
• C. Glands
• D. Hormones
• E. All of the above

Answer 1

The correct option is D Hormones

• Neurotransmitters are molecules used for direct signalling between neurons, usually by physical contact at a synapse.
• So epinephrine/adrenaline is released by the adrenal gland into the bloodstream as a hormone whereas norepinephrine/noradrenaline is released by neurons in the brain as a neurotransmitter. Hence, Hormones has neurotransmitters as their effector cells.

So, the correct answer is 'Hormones'.
