Reflex Arc, Synapses and Neurotransmitters

• How do Neurons Pass Impulses

  Neurons do not touch each other

  The gap between neurons -> synapse
• How does the Impulse reach the Synapse (Process)

  • It travels along neurons and reaches synapse
  • Chemical Transmitter Substance (Called Neurotransmitters) released from first neuron
  • Then diffuses across synapse
  • Triggers off impulse in second neuron
  • Ensures impulses travel in one direction
