Mechanism of synaptic transmission.jpg

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.

When action potential reaches a synapse, the synaptic vesicle fuse with the pre post synaptic membrane.

The receptors for the synaptic transmitters are mainly located on the pre post synaptic membrane.

When a membrane of a neuron is stimulated, the membrane hyperpolarizes. true false
