The process whose specific outcome is the progression of the ureteric bud over time, from its formation to the mature structure [goid 1657] [pmid 15130495] [evidence IMP]; The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis) [goid 6935] [evidence IEA]; The series of molecular signals generated as a consequence of a G-protein coupled receptor binding to its physiological ligand [goid 7186] [evidence IEA]; 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) [goid 7275] [evidence IEA]; The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state [goid 7399] [pmid 9813312] [evidence TAS]; The migration of mesodermal cells during gastrulation to help establish the multilayered body plan of the organism [goid 7509] [pmid 10102268] [evidence IMP]; The series of events required for an organism to receive an olfactory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Olfaction involves the detection of chemical composition of an organism's ambient medium by chemoreceptors [goid 7608] [pmid 10102269] [evidence TAS]; The process by which a neuronal cell in a multicellular organism interprets its surroundings [goid 8038] [pmid 10432110] [evidence TAS]; The process by which the migration of an axon growth cone of a motor neuron is directed to a specific target site in response to a combination of attractive and repulsive cues [goid 8045] [pmid 10102268] [evidence TAS]; The orderly movement of glial cells, non-neuronal cells that provide support and nutrition, maintain homeostasis, form myelin, and participate in signal transmission in the nervous system [goid 8347] [pmid 10102268] [evidence IMP]; The process whereby 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 [goid 30154] [evidence IEA]; The process by which the migration of an axon growth cone of a retinal ganglion cell (RGC) is directed to its target in the brain in response to a combination of attractive and repulsive cues [goid 31290] [evidence IEA]; Any process that activates or increases the frequency, rate or extent of axonogenesis [goid 50772] [pmid 10197527] [evidence TAS]; Any process that initiates the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical [goid 50929] [pmid 10197527] [evidence IDA]; Any process that initiates the directed movement of a motile cell or organism towards a lower concentration in a concentration gradient of a specific chemical [goid 50929] [pmid 10102268] [evidence IMP]
