Meaning
A synapse is the gap between two neurons that an electrical impulse must pass from one neuron to the next.
About Synapses
- The synapse is a very small gap to ensure the impulse is passed quickly and without losing strength.
- Chemicals called neurotransmitters pass from one neuron to another across the synapse.
