The characteristic movement of an immature neuron from germinal zones to specific positions where they will reside as they mature.

The change in form that occurs when an epithelial cell progresses from its initial formation to its mature state.

The developmental growth that results in the elongation of a line that defines polarity or symmetry in an anatomical structure.

The vesicular release of classical neurotransmitter molecules from a presynapse, across a chemical synapse, the subsequent activation of neurotransmitter receptors at the postsynapse of a target cell (neuron, muscle, or secretory cell) and the effects of this activation on the postsynaptic membrane potential and ionic composition of the postsynaptic cytosol. This process encompasses both spontaneous and evoked release of neurotransmitter and all parts of synaptic vesicle exocytosis. Evoked transmission starts with the arrival of an action potential at the presynapse.

The directed movement of cytoplasmic constituents synthesized in the nurse cells to the oocyte.

Formation of a ventral indentation (furrow) from the blastoderm epithelium, which is internalized to form a tube in the interior of the embryo, marking the start of gastrulation.

The process during Drosophila embryogenesis whereby the ectodermal cells of the lateral epithelium stretch in a coordinated fashion to internalize the amnioserosa cells and close the embryo dorsally.

De novo generation of a long process of a neuron, including the terminal branched region. Refers to the morphogenesis or creation of shape or form of the developing axon, which carries efferent (outgoing) action potentials from the cell body towards target cells.

The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

The process whose specific outcome is the progression of the central nervous system over time, from its formation to the mature structure. The central nervous system is the core nervous system that serves an integrating and coordinating function. In vertebrates it consists of the brain and spinal cord. In those invertebrates with a central nervous system it typically consists of a brain, cerebral ganglia and a nerve cord.

The process whose specific outcome is the progression of the ventral cord over time, from its formation to the mature structure. The ventral cord is one of the distinguishing traits of the central nervous system of all arthropods (such as insects, crustaceans and arachnids) as well as many other invertebrates, such as the annelid worms.

The acquisition and processing of information and/or the storage and retrieval of this information over time.

The process in 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.

Any process that modulates the frequency, rate or extent of the assembly or disassembly of actin filaments by the addition or removal of actin monomers from a filament.

Any process that modulates the surface configuration of a cell.

Any process that increases the rate, frequency or extent of the formation of a lamellipodium, a thin sheetlike extension of the surface of a migrating cell.

Any process that decreases the rate, frequency or extent of neuron projection development. Neuron projection development is the process whose specific outcome is the progression of a neuron projection over time, from its formation to the mature structure. A neuron projection is any process extending from a neural cell, such as axons or dendrites (collectively called neurites).

The recognition of molecules at the central nervous system midline choice point by an axon growth cone; this choice point determines whether the growth cone will cross the midline.

The phosphorylation of peptidyl-tyrosine to form peptidyl-O4'-phospho-L-tyrosine.

The phosphorylation of peptidyl-tyrosine to form peptidyl-O4'-phospho-L-tyrosine.

The process in which a branchiomotor neuron growth cone is directed to a specific target site. Branchiomotor neurons are located in the hindbrain and innervate branchial arch-derived muscles that control jaw movements, facial expression, the larynx, and the pharynx.

Any process that affects the structure and integrity of a protein, altering the likelihood of its degradation or aggregation.

Any process that modulates the frequency, rate or extent of any process in which a protein is transported to, or maintained in, a specific location.

Any process that stops, prevents, or reduces the frequency, rate or extent of synaptic growth at neuromuscular junction.

The phosphorylation by a protein of one or more of its own amino acid residues (cis-autophosphorylation), or residues on an identical protein (trans-autophosphorylation).

Any process that activates or increases the frequency, rate or extent of directed movement of proteins from the nucleus into the cytoplasm.

The process whose specific outcome is the progression of the compound eye over time, from its formation to the mature structure. The compound eye is an organ of sight that contains multiple repeating units, often arranged hexagonally. Each unit has its own lens and photoreceptor cell(s) and can generate either a single pixelated image or multiple images, per eye.

The process in which the anatomical structures of a dendrite are generated and organized.

The chemotaxis process that directs the migration of a photoreceptor cell axon growth cone to its target in the optic lobe in response to a combination of attractive and repulsive cues.

The chemotaxis process that directs the migration of a photoreceptor cell axon growth cone to its target in the optic lobe in response to a combination of attractive and repulsive cues.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

A cell junction that forms a connection between two or more cells in a multicellular organism; excludes direct cytoplasmic junctions such as ring canals.

A cell junction at which anchoring proteins (cadherins or integrins) extend through the plasma membrane and are attached to actin filaments.

A cell-substrate junction found at the terminal anchorage site of skeletal muscle cells to tendons.

The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.

The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region.

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.

The region that lies just beneath the plasma membrane on the apical edge of a cell.
