The nervous system responds rapidly to stimuli by sending electrical action potentials along neurons, which in turn transmit these action potentials to their target cells using neurotransmitters, the chemical messenger of the nervous system.
Your question: The nervous system affects target organs through the release of chemicals called what?
My answer: Neurotransmitters.
Why is my answer correct? Good question! Allow me to explain: The nervous system responds rapidly to stimuli by sending electrical action potentials along neurons, which in turn transmit these action potentials to their target cells using neurotransmitters, the chemical messenger of the nervous system.
