The propagation of the potential
along the axon the region
immediately anterior the presynaptic
membrane causing permeability to
calcium ions change and these ions
enter the cell. In presynaptic area
of the there are many
neurotransmitter-repleted that
by means of activated by the
calcium release the
neurotransmitters into synaptic
cleft. The neurotransmitters bind
to specific receptors the postsynaptic
membrane. (The of
neurotransmitters to their is
reversible, i.e., the
are not consumed after process.)
With the binding neurotransmitters to
the post receptors the
permeability of postsynaptic
membrane is altered the
depolarization that will to the first
action of the post synaptic
begins.
