Nerv06/introduction/mechanism of synaptic transmission

POINT!

The synaptic transmitter connects to the receptors on the post-synaptic membrane and generates an action potential

synaptic transmission is a chemical process.

When an action potential <1> reaches the nerve ending of the pre-synaptic neuron, the synaptic vesicle <2> moves towards the pre-synaptic membrane and then <3> fuses with the pre-synaptic membrane. With this movement, <4> the synaptic transmitter is released, and then <5> connects to the receptor on the post-synaptic membrane. This causes the post-synaptic membrane to depolarize and an <6> action potential is generated.
