In almost all cases, they are separated by an extremely narrow space called the synaptic cleft, over which nerve impulses are transmitted. These places where one neuron communicates with another are called synapses.   The axon, also called the nerve fibre, is a tubelike extension of a neuron cell body.he action of a neurotransmitter on a neuron is to open ion pores which allow Sodium ions to enter the neuron.
