synapse
When an impulse reaches an axon terminal, a _____________ substance is released in to the gap
neurotransmitter. This is detected by the next neurone which generates a new impulse
Synapses slow down…
neurotransmission
Why are synapses useful in the nervous system?
The create fresh impulses. The original impulse doesn’t lose it’s strength
Allow impulses to flow in one direction
