    GO ID   Ontology GO Term Definition
    5576   Extracellular Region  The Space External to the Outermost Structure of a Cell. For Cells Without External Protective or External Encapsulating Structures This Refers to Space Outside of the Plasma Membrane. This Term Covers the Host Cell Environment Outside an Intracellular Parasite. 
    72556   Other Organism Presynaptic Membrane  A Presynaptic Membrane That Is Part of Another Organism I.e. a Secondary Organism with Which the First Organism Is Interacting. a Presynaptic Membrane Is 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.
