Correct answer: C. Neurotransmitters

  • A. Enzymes
  • B. Chemoreceptors
  • C. Neurotransmitters
  • D. Hormones

Explanation

In the nervous system, chemical messengers that transmit signals between neurons or from neurons to other cells, such as muscle cells, are called "neurotransmitters." Neurotransmitters are released from the presynaptic neuron's terminal into the synaptic cleft, where they bind to receptors on the postsynaptic membrane and initiate a response in the receiving cell.

About Coordination and Control

Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
