| Identifier | Name | Description |
|---|---|---|
| GO:0043231 | intracellular membrane-bounded organelle | Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. |
| GO:0016023 | cytoplasmic membrane-bounded vesicle | A membrane-bounded vesicle found in the cytoplasm of the cell. |
| GO:0044464 | cell part | Any constituent part of a cell, the basic structural and functional unit of all organisms. |
| GO:0044444 | cytoplasmic part | Any constituent part of the cytoplasm, all of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0044424 | intracellular part | Any constituent part of the living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. |
| GO:0005575 | cellular_component | The part of a cell or its extracellular environment in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together. |
| GO:0005623 | cell | The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope. |
| GO:0043227 | membrane-bounded organelle | Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. |
| GO:0043226 | organelle | Organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, and prokaryotic structures such as anammoxosomes and pirellulosomes. Excludes the plasma membrane. |
| 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:0031410 | cytoplasmic vesicle | A vesicle formed of membrane or protein, found in the cytoplasm of a cell. |
| GO:0031982 | vesicle | Any small, fluid-filled, spherical organelle enclosed by membrane or protein. |
| GO:0031988 | membrane-bounded vesicle | Any small, fluid-filled, spherical organelle enclosed by a lipid bilayer. |
| GO:0044463 | cell projection part | Any constituent part of a cell projection, a prolongation or process extending from a cell, e.g. a flagellum or axon. |
| GO:0042995 | cell projection | A prolongation or process extending from a cell, e.g. a flagellum or axon. |
| GO:0045202 | synapse | The junction between a nerve fiber of one neuron and another neuron or muscle fiber or glial cell; the site of interneuronal communication. 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:0044456 | synapse part | Any constituent part of a synapse, the junction between a nerve fiber of one neuron and another neuron or muscle fiber or glial cell. |
| GO:0097458 | neuron part | Any constituent part of a neuron, the basic cellular unit of nervous tissue. A typical neuron consists of a cell body (often called the soma), an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the nervous system. |
| GO:0008021 | synaptic vesicle | A secretory organelle, some 50 nm in diameter, of presynaptic nerve terminals; accumulates in high concentrations of neurotransmitters and secretes these into the synaptic cleft by fusion with the 'active zone' of the presynaptic plasma membrane. |
| GO:0043005 | neuron projection | A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
| 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:0033267 | axon part | A part of an axon, a cell projection of a neuron. |
| 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:0043679 | axon terminus | 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. |
| GO:0044306 | neuron projection terminus | The specialized, terminal region of a neuron projection such as an axon or a dendrite. |
| GO:1990475 | synaptic vesicle, recycling pool | A pool of synaptic vesicles that repopulate vacancies within the readily releasable pool (RRP) of synaptic vesicles, and require more significant stimuli than the RRP in order to release neurotransmitter; contains about 10-15% of the total number of synaptic vesicles at a resting terminal bouton. |
