presynaptic membrane

pre·syn·ap·tic mem·brane

that part of the plasma membrane of an axon terminal that faces the plasma membrane of the neuron or muscle fiber with which the axon terminal establishes a synaptic junction; many synaptic junctions exhibit structural presynaptic characteristics, such as conic electron-dense internal protrusions, which distinguish it from the remainder of the axon's plasma membrane.
See also: synapse.

pre·syn·ap·tic membrane

(prē'si-nap'tik mem'brān) That part of the plasma membrane of an axon terminal that faces the plasma membrane of the neuron or muscle fiber with which the axon terminal establishes a synaptic junction.
See also: synapse

presynaptic membrane

the excitable membrane of the axon terminal next to the dendrite at a synapse.
