(a) Nerve impulse travels from dendritic end towards axonal end
(b) At the dendritic end electrical impulses bring about the release
of some chemicals which generate an electrical impulse at the
axonal end of another neuron
(c) The chemicals released from the axonal end of one neuron cross
the synapse and generate a similar electrical impulse in a
dendrite of another neuron
(d) A neuron transmits electrical impulses not only to another
neuron but also to muscle and gland cells
