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 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 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 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.

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.

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

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 projection of branches of an open tracheal system towards their target tissues. An example of this is found in Drosophila melanogaster.

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

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 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.

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

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

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.
