Question
How does a nerve impulse travel from one to another neuron?
Solution
Neural messages pass from the dendrites to the next neuron, jumping across the synapse. The membranes on either side of the synapse are called 'presynaptic membrane' (of transmitting neuron) and 'postsynaptic membrane' (of the receiving neuron). The space lying between membranes is the synaptic cleft.
