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 gonad over time, from its formation to the mature structure. The gonad is an animal organ that produces gametes; in some species it also produces hormones.

The process in which the anatomical structures of the outflow tract are generated and organized. The outflow tract is the portion of the heart through which blood flows into the arteries.

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.

Determination of where the salivary gland forms, the total number of salivary gland cells and how many cells are allocated to each of the specialised cell types within the salivary gland.

The process whose specific outcome is the progression of the mushroom body over time, from its formation to the mature structure. The mushroom body is composed of the prominent neuropil structures of the insect central brain, thought to be crucial for olfactory associated learning. These consist mainly of a bulbous calyx and tightly packaged arrays of thin parallel fibers of the Kenyon cells.

Any process that activates or increases the rate or extent of cell adhesion to another cell.

The process whose specific outcome is the progression of the embryonic heart tube over time, from its formation to the mature structure. The heart tube forms as the heart rudiment from the heart field.

The process whose specific outcome is the progression of the central complex over time, from its formation to the mature structure. The central complex region of the insect brain is thought to be crucial for control of locomotive behavior. Located in the middle of the two protocerebral hemispheres, it comprises four neuropilar regions, the fan-shaped body, the ellipsoid body, the protocerebral bridge and the paired noduli.

Any process that modulates the frequency, rate or extent of epithelial cell migration, open tracheal system.

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

The process in which a neuronal cell in a multicellular organism interprets its surroundings.

The process in which a neuronal cell in a multicellular organism interprets signals produced by potential target cells, with which it may form synapses.

The process in which a cell becomes capable of differentiating autonomously into a cardioblast cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. A cardioblast is a cardiac precursor cell. It is a cell that has been committed to a cardiac fate, but will undergo more cell division rather than terminally differentiating.

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.

The synchronization of a circadian rhythm to environmental time cues such as light.

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 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 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 process in which a neuronal cell in a multicellular organism recognizes chemorepellent signals that inhibit its growth toward the source.

Any process that activates or increases the frequency, rate or extent of cell migration.

A series of molecular signals initiated by the binding of a SLIT protein to a Roundabout (ROBO) family receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The cellular homeostatic process that preserves a muscle cell in a stable functional or structural state.

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

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

Any process that modulates the frequency, rate or extent of dendrite development.

The process in which the migration of a dendrite is directed to a specific target site 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.

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 in which a neuronal cell in a multicellular organism recognizes chemorepellent signals that inhibit its growth toward the source.

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 membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

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.

Any small, fluid-filled, spherical organelle enclosed by membrane.

A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.

The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.

The migrating motile tip of a growing nerve cell axon.

A protein-carbohydrate complex that consists of a transmembrane roundabout (Robo) receptor, an extracellular Slit ligand and heparin/heparan sulfate.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
