Post synaptic receptor antagonist
WebThe post-synaptic terminal may be a neuron or non-neuronal cell. It contains receptors for neurotransmitters that are linked to some ion channels. The binding of neurotransmitters to these receptors results in the opening of ion channels, the ion diffuse across the cell, and an action potential is generated in the postsynaptic cell.
