| | GO:0015629 | | actin cytoskeleton | | The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes. |
| | GO:0030424 | | axon | | 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. |
| | GO:0044295 | | axonal growth cone | | The migrating motile tip of a growing nerve cell axon. |
| | GO:0030054 | | cell junction | | A cellular component that forms a specialized region of connection between two or more cells or between a cell and the extracellular matrix. At a cell junction, anchoring proteins extend through the plasma membrane to link cytoskeletal proteins in one cell to cytoskeletal proteins in neighboring cells or to proteins in the extracellular matrix. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| | GO:0005768 | | endosome | | A vacuole to which materials ingested by endocytosis are delivered. |
| | GO:0030175 | | filopodium | | Thin, stiff, actin-based protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal or dendritic growth cone, or a dendritic shaft. |
| | GO:0030426 | | growth cone | | The migrating motile tip of a growing neuron projection, where actin accumulates, and the actin cytoskeleton is the most dynamic. |
| | GO:0043229 | | intracellular organelle | | Organized structure of distinctive morphology and function, occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton. Excludes the plasma membrane. |
| | GO:0030027 | | lamellipodium | | A thin sheetlike process extended by the leading edge of a migrating cell or extending cell process; contains a dense meshwork of actin filaments. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0045121 | | membrane raft | | Any of the small (10-200 nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched membrane domains that compartmentalize cellular processes. Small rafts can sometimes be stabilized to form larger platforms through protein-protein and protein-lipid interactions. |
| | GO:0043005 | | neuron projection | | A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
| | GO:0043025 | | neuronal cell body | | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
| | GO:0048471 | | perinuclear region of cytoplasm | | Cytoplasm situated near, or occurring around, the nucleus. |
| | GO:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| | GO:0045202 | | synapse | | The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. |
| | GO:0070044 | | synaptobrevin 2-SNAP-25-syntaxin-1a complex | | A SNARE complex that contains synaptobrevin 2 (VAMP2), SNAP-25, and syntaxin 1a (or orthologs thereof). |
| | GO:0070032 | | synaptobrevin 2-SNAP-25-syntaxin-1a-complexin I complex | | A SNARE complex that contains synaptobrevin 2 (VAMP2), SNAP-25, syntaxin 1a, and complexin I (or orthologs thereof). |
| | GO:0070033 | | synaptobrevin 2-SNAP-25-syntaxin-1a-complexin II complex | | A SNARE complex that contains synaptobrevin 2 (VAMP2), SNAP-25, syntaxin 1a, and complexin II (or orthologs thereof). |
| | GO:0043195 | | terminal bouton | | 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. |
| | GO:0008076 | | voltage-gated potassium channel complex | | A protein complex that forms a transmembrane channel through which potassium ions may cross a cell membrane in response to changes in membrane potential. |
