Term Detail
GO term:presynaptic membrane
Synonym: pre-synaptic membrane
GO id:GO:0042734
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.
Number of paths to term: 13
