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

The attachment of a plasma membrane adhesion molecule in one cell to an identical molecule in an adjacent cell.

A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).

Ensuring that a tube in an open tracheal system is of the correct length.

Any process that modulates the frequency, rate or extent of hemocyte proliferation. Hemocytes are blood cells associated with a hemocoel (the cavity containing most of the major organs of the arthropod body) which are involved in defense and clotting of hemolymph, but not involved in transport of oxygen. An example of this is found in Drosophila melanogaster.

The process that gives rise to the patterns of cell differentiation in the chitin-based larval cuticle. An example of this is found in Drosophila melanogaster.

A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of an imaginal disc-derived wing hair. A wing hair is an actin-rich, polarized, non-sensory apical projection that protrudes from each of the approximately 30,000 wing epithelial cells. An example of this is found in Drosophila melanogaster.

Determination of the site in the cell of an imaginal disc-derived wing at which a prehair initiates outgrowth. Restriction of prehair initiation to the distalmost part of a cell is essential to ensure that each wing epithelial cell produces one adult hair that points distally.

The specification of polarized ommatidia. Ommatidia occur in two chiral forms. The trapezoidal arrangement of photoreceptors in the dorsal part of the eye is the mirror image of that in the ventral part.

Any process that activates or increases the frequency, rate or extent of axon extension.

Long distance growth of a single axon process involved in cellular development.

The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes. In this pathway, the activated receptor signals via downstream effectors that result in the inhibition of beta-catenin phosphorylation, thereby preventing degradation of beta-catenin. Stabilized beta-catenin can then accumulate and travel to the nucleus to trigger changes in transcription of target genes.

The series of molecular signals initiated by binding of a Wnt protein to a receptor on the surface of the target cell where activated receptors signal via downstream effectors including C-Jun N-terminal kinase (JNK) to modulate cytoskeletal elements and control cell polarity.

The orderly movement of a neuroblast from one site to another, often during the development of a multicellular organism or multicellular structure. A neuroblast is any cell that will divide and give rise to a neuron.

The orderly movement of a motor neuron from one site to another. A motor neuron is an efferent neuron that passes from the central nervous system or a ganglion toward or to a muscle and conducts an impulse that causes movement.

Any process that activates or increases the frequency, rate or extent of axon guidance.

A complex and coordinated series of cellular movements that occurs at the end of cleavage during embryonic development of most animals. The details of gastrulation vary from species to species, but usually result in the formation of the three primary germ layers, ectoderm, mesoderm and endoderm.

The process whose specific outcome is the progression of an embryo over time, from zygote formation until the end of the embryonic life stage. The end of the embryonic life stage is organism-specific and may be somewhat arbitrary; for mammals it is usually considered to be birth, for insects the hatching of the first instar larva from the eggshell.
