| 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: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: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: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:0014069 | postsynaptic density | An electron dense network of proteins within and adjacent to the postsynaptic membrane of an asymmetric, neuron-neuron synapse. Its major components include neurotransmitter receptors and the proteins that spatially and functionally organize them such as anchoring and scaffolding molecules, signaling enzymes and cytoskeletal components. |
| GO:0099572 | postsynaptic specialization | A network of proteins within and adjacent to the postsynaptic membrane. Its major components include neurotransmitter receptors and the proteins that spatially and functionally organize them such as anchoring and scaffolding molecules, signaling enzymes and cytoskeletal components. |
| 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: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:0044327 | dendritic spine head | Distal part of the dendritic spine, that carries the post-synaptic density. |
