A part of an axon, a cell projection of a neuron. The specialized, terminal region of a neuron projection such as an axon or a dendrite. 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. 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 button is a specialized region of it. 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 button is a specialized region of it. Any constituent part of a cell projection, a prolongation or process extending from a cell, e.g. a flagellum or axon.
