| biological process |
|---|
| | GO:0030154 | | cell differentiation | | The process in which relatively unspecialized cells, e.g. embryonic or regenerative cells, acquire specialized structural and/or functional features that characterize the cells, tissues, or organs of the mature organism or some other relatively stable phase of the organism's life history. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. |
| | GO:0006897 | | endocytosis | | A vesicle-mediated transport process in which cells take up external materials or membrane constituents by the invagination of a small region of the plasma membrane to form a new membrane-bounded vesicle. |
| | GO:0060988 | | lipid tube assembly | | The aggregation, arrangement and bonding together of a set of macromolecules to form a macromolecular complex that contains a tube of lipid surrounded by a protein coat involved in membrane shaping of vesicle membranes as they fuse or undergo fission. |
| | GO:0007275 | | multicellular organism development | | The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult). |
| | GO:0043547 | | positive regulation of GTPase activity | | Any process that activates or increases the activity of a GTPase. |
| | GO:0043065 | | positive regulation of apoptotic process | | Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process. |
| | GO:0048711 | | positive regulation of astrocyte differentiation | | Any process that activates or increases the frequency, rate or extent of astrocyte differentiation. |
| | GO:0045807 | | positive regulation of endocytosis | | Any process that activates or increases the frequency, rate or extent of endocytosis. |
| | GO:0071156 | | regulation of cell cycle arrest | | Any process that modulates the rate, frequency, or extent of cell cycle arrest, the process in which the cell cycle is halted during one of the normal phases. |
| | GO:0030100 | | regulation of endocytosis | | Any process that modulates the frequency, rate or extent of endocytosis. |
| | GO:0045664 | | regulation of neuron differentiation | | Any process that modulates the frequency, rate or extent of neuron differentiation. |
| cellular component |
|---|
| | GO:0031674 | | I band | | A region of a sarcomere that appears as a light band on each side of the Z disc, comprising a region of the sarcomere where thin (actin) filaments are not overlapped by thick (myosin) filaments; contains actin, troponin, and tropomyosin; each sarcomere includes half of an I band at each end. |
| | GO:0030315 | | T-tubule | | Invagination of the plasma membrane of a muscle cell that extends inward from the cell surface around each myofibril. The ends of T-tubules make contact with the sarcoplasmic reticulum membrane. |
| | GO:0030018 | | Z disc | | Platelike region of a muscle sarcomere to which the plus ends of actin filaments are attached. |
| | 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:0043194 | | axon initial segment | | 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. |
| | 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:0044300 | | cerebellar mossy fiber | | An axon arising from cerebellar projecting cells in the cochlea, vestibular nuclei, spinal cord, reticular formation, cerebellar nuclei and basilar pontine nuclei. Mossy fibers enter through all three cerebellar peduncles and send collaterals to the deep cerebellar nuclei, then branch in the white matter and terminate in the granule cell layer. Through this branching, a given mossy fiber can innervate several folia. Mossy fibers synapse on granule cells. The synaptic contacts are made at enlargements along the length of the mossy fiber called mossy fiber rosettes. The enlargements of the rosettes give the axons as "mossy" appearance in Golgi stained preparations. |
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0060987 | | lipid tube | | A macromolecular complex that contains a tube of lipid surrounded by a protein coat. |
| | GO:0005874 | | microtubule | | Any of the long, generally straight, hollow tubes of internal diameter 12-15 nm and external diameter 24 nm found in a wide variety of eukaryotic cells; each consists (usually) of 13 protofilaments of polymeric tubulin, staggered in such a manner that the tubulin monomers are arranged in a helical pattern on the microtubular surface, and with the alpha/beta axes of the tubulin subunits parallel to the long axis of the tubule; exist in equilibrium with pool of tubulin monomers and can be rapidly assembled or disassembled in response to physiological stimuli; concerned with force generation, e.g. in the spindle. |
| | GO:0033268 | | node of Ranvier | | An axon part that is a gap in the myelin where voltage-gated sodium channels cluster and saltatory conduction is executed. |
| | GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
| | GO:0008021 | | synaptic vesicle | | A secretory organelle, typically 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:0043196 | | varicosity | | Non-terminal inflated portion of the axon, containing the specialized apparatus necessary to release neurotransmitters. |
