1.) Preview: The nervous system consists of billions of cells called neurons. Neurons communicate with each other by receiving information through the dendrite, sending the impulse through the axon. When this impulse reaches the axon terminal end there is gap to the next neuron. The axon terminal end signals neurotransmitters to go across the gap and combine receptor sites. This allows the impulse or “message” to go to the next neuron. There are many different types of neurotransmitters. Researchers are studying how some drugs mimic neurotransmitter and other stop neurotransmitters from working.
