Coordinated organization of groups of cells in the plane of an epithelium, such that they all orient to similar coordinates.

The morphogenetic process in which the anatomical structures of a polarized epithelium are generated and organized. A polarized epithelium is an epithelium where the epithelial sheet is oriented with respect to the planar axis.

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

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

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

Coordinated organization of groups of cells in a tissue, such that they all orient to similar coordinates.

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

Division of the 14 parasegments of the embryo into anterior and posterior compartments; exemplified by the actions of the segment polarity gene products.

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

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 the R3/R4 photoreceptors commit to their cell fate. R3 and R4 are paired photoreceptors which contribute the outer rhabdomeres.

The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell and ending with a change in cell state.

The process in which photoreceptors are arranged in ommatidia in the dorsal and ventral fields to be mirror images. The polarity is established in the imaginal discs concurrently with cell fate specification.

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 attachment of one cell to another cell via adhesion molecules that require the presence of calcium for the interaction.

The attachment of one cell to another cell via adhesion molecules that require the presence of calcium for the interaction.

The process whose specific outcome is the progression of the dendrite over time, from its formation to the mature structure. A dendrite is a freely branching protoplasmic process of a nerve cell.

Any process that activates or increases the frequency, rate or extent of Wnt signal transduction.

Any process that stops, prevents, or reduces the frequency, rate or extent of the Wnt signaling pathway.

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

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 stops, prevents, or reduces the frequency, rate or extent of the Notch signaling pathway.

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

The process whose specific outcome is the progression of the R3 and R4 pair of photoreceptors in the eye over time, from their formation to the mature structures. R3 and R4 are paired photoreceptors that contribute to the outer rhabdomeres. An example of this process is found in Drosophila melanogaster.

The process in which the anatomical structures of a dendrite are generated and organized. A dendrite is a freely branching protoplasmic process of a nerve cell.

Any process that modulates the frequency, rate or extent of axonogenesis, the generation of an axon, the long process of a neuron.

Any process that modulates the frequency, rate or extent of synapse assembly, the aggregation, arrangement and bonding together of a set of components to form a synapse.

The process in which dendrites recognize and avoid contact with sister dendrites from the same cell.

Any process that modulates the rate, frequency or extent of the establishment of planar polarity, the coordinated organization of groups of cells in a tissue, such that they all orient to similar coordinates.

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