Nervous system summary
... The action potential travels down the axon until the impulse reaches the axon terminal. The impulse must travel across the space between the axon terminal and the dendrites of the next neuron. This space between the two neurons is called the synaptic cleft. The axon terminal releases neurotransmitte ...
