Regions within compact myelin in which the cytoplasmic faces of the enveloping myelin sheath are not tightly juxtaposed, and include cytoplasm from the cell responsible for making the myelin. Schmidt-Lanterman clefts occur in the compact myelin internode, while lateral loops are analogous structures found in the paranodal region adjacent to the nodes of Ranvier. 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. A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. Any of the smaller branches of an axon that emanate from the main axon cylinder. The main axonal trunk, as opposed to the collaterals. A region of an axon near a node of Ranvier that is between the paranode and internode regions. A type of intermediate filament found in the core of neuronal axons. Neurofilaments are heteropolymers composed of three type IV polypeptides: NF-L, NF-M, and NF-H (for low, middle, and high molecular weight). Neurofilaments are responsible for the radial growth of an axon and determine axonal diameter. An axon part that is located adjacent to the nodes of Ranvier and surrounded by lateral loop portions of myelin sheath. Any constituent part of a cell projection, a prolongation or process extending from a cell, e.g. a flagellum or axon. A prolongation or process extending from a cell, e.g. a flagellum or axon. The migrating motile tip of a growing nerve cell axon. A spine that originates from the axon, usually from the initial segment. A part of an axon, a cell projection of a neuron. Portion of the axon proximal to the neuronal cell body, at the level of the axon hillock. The action potentials that propagate along the axon are generated at the level of this initial segment. An axon part that is located between the nodes of Ranvier and surrounded by compact myelin sheath. An axon part that is a gap in the myelin where voltage-gated sodium channels cluster and saltatory conduction is executed. 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. Non-terminal inflated portion of the axon, containing the specialized apparatus necessary to release neurotransmitters. Any constituent part of a cell, the basic structural and functional unit of all organisms. Portion of the neuronal cell soma from which the axon originates. 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. The portion of the plasma membrane surrounding an axon; it is a specialized trilaminar random mosaic of protein molecules floating within a fluid matrix of highly mobile phospholipid molecules, 7-8 nm in thickness.
