Terms & Properties

Concept Unique Identifier (CUI): C0206181

NCI Thesaurus Code: C33398  (see NCI Thesaurus info)

Semantic Type: Cell Component

NCIt Definition: An area at the end of an axon that contains neurotransmitters in synaptic vesicles.

GO Definition: Terminal inflated portion of the axon, containing the specialized apparatus necessary to release neurotransmitters. The axon terminus is considered to be the whole region of thickening and the terminal bouton is a specialized region of it. [GOC:dph, GOC:mc, GOC:nln, PMID:10218156, PMID:8409967]

MSH Definition: The distal terminations of axons which are specialized for the release of neurotransmitters. Also included are varicosities along the course of axons which have similar specializations and also release transmitters. Presynaptic terminals in both the central and peripheral nervous systems are included.
