Postsynaptic membrane

postsynaptic membrane

That part of the plasma membrane of a neuron or muscle fibre with which an axon terminal forms a synaptic junction; in many instances, at least part of such a small postsynaptic membrane patch shows characteristic morphological modifications such as greater thickness and higher electron-density, believed to correspond to the transmitter-sensitive receptor site of such synapses. A membrane found in the axon of a neurone capable of receiving nerve impulses.
