Name: retinal ganglion cell
Synonyms: gangliocyte, RGC
Definition: The set of neurons that receives neural inputs via bipolar, horizontal and amacrine cells. The axons of these cells make up the optic nerve.
Ontology: Anatomy Ontology [ZFA:0009310]
Name: axon
Synonyms:
Definition: The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.

Name: presynaptic active zone
Synonyms: pre-synaptic active zone, pre-synaptic active zone component, presynaptic specialization
Definition: A specialized region of the plasma membrane and cell cortex of a presynaptic neuron; encompasses a region of the plasma membrane where synaptic vesicles dock and fuse, and a specialized cortical cytoskeletal matrix.
