synapses

• how do signals pass from one neuron to another?

  neurons are not connected so signals pass over a synapse
• what happens when an action potential reaches the end of a neuron?

  it triggers the release of neurotransmitters which disperse across the synapse
• what do the neurotransmitters do?

  they bind to receptor molecules on the next neuron (post synaptic) and generates a new action potential
