|
During transmission across a typical chemical synapse,
|
|
neurotransmitters cause the release of vesicles.
|
|
|
action potentials make the vesicles fuse to each other.
|
|
|
vesicles diffuse to and fuse to the postsynaptic membrane.
|
|
|
neurotransmitters bind to receptors on the postsynaptic cell.
|
Explanation:
Detailed explanation-1: -At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.
Detailed explanation-2: -As a result of the action potential, the chemical transmitter acetylcholine (ACh) is released into the synaptic cleft. ACh diffuses across the synaptic cleft and binds to special receptors on the postsynaptic or the postjunctional membrane.
Detailed explanation-3: -The neurotransmitter diffuses across the synaptic cleft and binds to receptor proteins on the postsynaptic membrane.
