The information that are transmitted along the neurons in the form of electric impulses is called as nerve impulse.
(i) Dendrites (towards the cell)
(ii) Axon (away from the cell body)
The information flows from one neuron to another neuron through synapse. Presynaptic neuron and the postsynaptic neuron are separated by a small gap — the synaptic cleft. The synaptic cleft is filled with extracellular fluid.
