Term Information

Accession
GO:0042734
Name
presynaptic membrane
Ontology
cellular_component
Synonyms
pre-synaptic membrane, presynaptic plasma membrane
Alternate IDs
None
Definition
A specialized area of membrane of the 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 conical, electron-dense internal protrusions, that distinguish it from the remainder of the axon plasma membrane.
