Mechanism of synaptic transmission

POINT!

The synaptic transmitter combines with the receptor in the post-synaptic membrane and induces action potentials.

The synaptic transmission is chemical.

When ① action potential reaches the nerve ending of pre-synaptic neuron,

② the synaptic vesicle move towards, and ③ fuses with the presynaptic membrane. This ④ releases the synaptic transmitter, which ⑤ combines with the receptor and ⑥ induces action potential in the post-synaptic membrane.
