| GO:0005737 | cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005575 | cellular_component | A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology: (1) the cellular anatomical entity where a gene product carries out a molecular function (e.g., plasma membrane, cytoskeleton) or membrane-enclosed compartments (e.g., mitochondrion); (2) virion components, where viral proteins act, and (3) the stable macromolecular complexes of which gene product are parts (e.g., the clathrin complex). |
| GO:0005622 | intracellular anatomical structure | A component of a cell contained within (but not including) the plasma membrane. In eukaryotes it includes the nucleus and cytoplasm. |
| GO:0110165 | cellular anatomical structure | A part of a cellular organism consisting of a material entity with granularity above the level of a protein complex but below that of an anatomical system. Note that cellular organisms exclude viruses. |
| 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: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:0031974 | membrane-enclosed lumen | The enclosed volume within a sealed membrane or between two sealed membranes. Encompasses the volume enclosed by the membranes of a particular organelle, e.g. endoplasmic reticulum lumen, or the space between the two lipid bilayers of a double membrane surrounding an organelle, e.g. nuclear envelope lumen. |
| GO:0070013 | intracellular organelle lumen | An organelle lumen that is part of an intracellular organelle. |
| GO:0043233 | organelle lumen | The internal volume enclosed by the membranes of a particular organelle; includes the volume enclosed by a single organelle membrane, e.g. endoplasmic reticulum lumen, or the volume enclosed by the innermost of the two lipid bilayers of an organelle envelope, e.g. nuclear lumen. |
| GO:0012505 | endomembrane system | A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles. |
| GO:0031410 | cytoplasmic vesicle | A vesicle found in the cytoplasm of a cell. |
| GO:0097708 | intracellular vesicle | Any vesicle that is part of the intracellular region. |
| GO:0031982 | vesicle | Any small, fluid-filled, spherical organelle enclosed by membrane. |
| GO:0120025 | plasma membrane bounded cell projection | A prolongation or process extending from a cell and that is bounded by plasma membrane, e.g. a cilium, lamellipodium, or axon. |
| GO:0042995 | cell projection | A prolongation or process extending from a cell, e.g. a flagellum or axon. |
| GO:0098794 | postsynapse | The part of a synapse that is part of the post-synaptic cell. |
| GO:0045202 | synapse | The junction between an axon of one neuron and a dendrite of another neuron, a muscle fiber or a glial cell. As the axon approaches the synapse it enlarges into a specialized structure, the presynaptic terminal bouton, which contains mitochondria and synaptic vesicles. At the tip of the terminal bouton 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 terminal bouton secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. |
| 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, or between two membrane-bound components of a cell, such as flagella. |
| GO:0043005 | neuron projection | A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
| GO:0030425 | dendrite | A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body. |
| GO:0097447 | dendritic tree | The entire complement of dendrites for a neuron, consisting of each primary dendrite and all its branches. |
| GO:0036477 | somatodendritic compartment | The region of a neuron that includes the cell body (cell soma) and dendrite(s), but excludes the axon. |
| GO:0060205 | cytoplasmic vesicle lumen | The volume enclosed by a cytoplasmic vesicle. |
| GO:0031983 | vesicle lumen | The volume enclosed by the membrane or protein that forms a vesicle. |
| GO:0043197 | dendritic spine | A small, membranous protrusion from a dendrite that forms a postsynaptic compartment, typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable:they can be thin, stubby, mushroom, or branched, with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity. |
| GO:0044309 | neuron spine | A small membranous protrusion, often ending in a bulbous head and attached to the neuron by a narrow stalk or neck. |
| GO:0097444 | spine apparatus | A specialization of the endomembrane system found in some classes of dendritic spines consisting of two or more closely apposed lamellae with interspersed electron dense material. The endomembrane component is continuous with the smooth endoplasmic reticulum. |
| GO:0098899 | spine apparatus lumen | The volume enclosed by the spine apparatus membrane. |
