What happens if the correct ligand binds to ligand-gated sodium channel in a post-synaptic neuron?

Post-synaptic neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.

Explanation:

Postsynaptic neuron:

These are the neurons that is present after the gap called synapse. These neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.

There are number of neurotransmitter. These includes

GABA ergic: This neurotransmitter is often inhibitory.

glutamatergic: This neurotransmitter is often excitatory.

Adrenergic: This neurotransmitter releases norepinephrine.

Cholinergic: This neurotransmitter activates vertebrate neuromuscular junction.
