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

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 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 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 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 orderly movement of epithelial cells during development of an open tracheal system. 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 whose specific outcome is the progression of the digestive tract mesoderm over time, from its formation to the mature structure. The digestive tract mesoderm is portion of the middle layer of the three primary germ layers of the embryo which will go on to form part of the digestive tract of the organism.

The migration of mesodermal cells during gastrulation to help establish the multilayered body plan of the organism.

The orderly movement of mesodermal cells from one site to another.

The orderly movement of a glial cell, non-neuronal cells that provide support and nutrition, maintain homeostasis, form myelin, and participate in signal transmission in the nervous system.

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.

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

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 rate or extent of cell adhesion to another cell.

The process in which a relatively unspecialized cell acquires specialized features of a neuron.

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

The process in which the migration of an axon growth cone is directed to a specific target site along the dorsal-ventral body axis in response to a combination of attractive and repulsive cues. The dorsal/ventral axis is defined by a line that runs orthogonal to both the anterior/posterior and left/right axes. The dorsal end is defined by the upper or back side of an organism. The ventral end is defined by the lower or front side of an organism.

The process in which the migration of an axon growth cone is directed to a specific target site along the dorsal-ventral body axis in response to a combination of attractive and repulsive cues. The dorsal/ventral axis is defined by a line that runs orthogonal to both the anterior/posterior and left/right axes. The dorsal end is defined by the upper or back side of an organism. The ventral end is defined by the lower or front side of an organism.

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.

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

Any process that stops, prevents, or reduces the frequency, rate or extent of axon extension involved in axon guidance.

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.

The process in which the migration of an axon growth cone of a sensory neuron is directed to a specific target site in response to a combination of attractive and repulsive cues. A sensory neuron is an afferent neuron conveying sensory impulses.

Any process that modulates the frequency, rate or extent of sensory neuron axon guidance.

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

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

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

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