The morphogenetic process in which the anatomical structures of the compound eye are generated and organized. The adult compound eye is a precise assembly of 700-800 ommatidia. Each ommatidium is composed of 20 cells, identified by cell type and position. An example of compound eye morphogenesis is found in Drosophila melanogaster.

Any cellular process that results in the specification, formation or maintenance of anisotropic intracellular organization or cell growth patterns.

A series of molecular signals initiated by the binding of an extracellular ligand to the receptor Notch on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

An intracellular protein kinase cascade containing at least a JNK (a MAPK), a JNKK (a MAPKK) and a JUN3K (a MAP3K). The cascade can also contain two additional tiers: the upstream MAP4K and the downstream MAP Kinase-activated kinase (MAPKAPK). The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell.

The process during Drosophila embryogenesis whereby the ectodermal cells of the lateral epithelium stretch in a coordinated fashion to internalize the amnioserosa cells and close the embryo dorsally.

The process during Drosophila embryogenesis whereby the ectodermal cells of the lateral epithelium stretch in a coordinated fashion to internalize the amnioserosa cells and close the embryo dorsally.

The process during Drosophila embryogenesis whereby the ectodermal cells of the lateral epithelium stretch in a coordinated fashion to internalize the amnioserosa cells and close the embryo dorsally.

The process whose specific outcome is the progression of an open tracheal system over time, from its formation to the mature structure. An open tracheal system is a respiratory system, a branched network of epithelial tubes that supplies oxygen to target tissues via spiracles. An example of this is found in Drosophila melanogaster.

Movement of the anterior ectoderm to the interior of the embryo.

The attachment of one cell to another cell via adhesion molecules, where both cells are part of the same organism.

Any process that modulates the surface configuration of an embryonic cell.

The process whose specific outcome is the progression of a chaeta over time, from its formation to the mature structure. A chaeta is a sensory multicellular cuticular outgrowth of a specifically differentiated cell.

Any process that modulates the frequency, rate or extent of attachment of a cell to another cell or to the extracellular matrix.

Any process that modulates the frequency, rate or extent of attachment of a cell to another cell or to the extracellular matrix.

Fusing of specific tracheal branches in an open tracheal system to branches from neighboring hemisegments to form a continuous tracheal network. Branch fusion is mediated by individual cells at the tip of each branch, which contact a similar cell and undergo a coordinated series of morphogenetic events that create a bicellular fusion joint.

The process in which a cell becomes capable of differentiating autonomously into a fusion cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. Fusion cells allow the interconnection of adjacent tracheal metameres during tracheal tube fusion.

Progression of the wing disc over time, from its initial formation through to its metamorphosis to form adult structures including the wing hinge, wing blade and pleura.

The aggregation, arrangement and bonding together of a set of components to form a nephrocyte diaphragm, a specialized cell-cell junction found between nephrocytes of the insect kidney.

Any process in which a protein is transported to, or maintained in, apical regions of the cell.

Any process that modulates the frequency, rate or extent of signal transduction mediated by the JNK cascade.

Signaling between cells of equivalent developmental potential that results in these cells adopting different developmental fates. An example is the suppression by cells with a particular fate of the adoption of the same fate by surrounding cells.

The process in which the anatomical structures of a neuron projection are generated and organized. A neuron projection is any process extending from a neural cell, such as axons or dendrites.

The process in which a trachea is generated and organized. The trachea is the portion of the airway that attaches to the bronchi as it branches.

A process in which a protein is transported to, or maintained in, the cell cortex.

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

A cell junction at which anchoring proteins (cadherins or integrins) extend through the plasma membrane and are attached to actin filaments.

A cell junction at which anchoring proteins (cadherins or integrins) extend through the plasma membrane and are attached to actin filaments.

A cell junction at which anchoring proteins (cadherins or integrins) extend through the plasma membrane and are attached to actin filaments.

An adherens junction which connects a cell to another cell.

A specialized cell-cell junction found between nephrocytes of the insect kidney, which is adapted for filtration of hemolymph. The insect nephrocyte is anatomically and functionally similar to the glomerular podocyte of vertebrates.

The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.

The region of the plasma membrane that includes the basal end and sides of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis.

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 region of a polarized cell that forms a tip or is distal to a base. For example, in a polarized epithelial cell, the apical region has an exposed surface and lies opposite to the basal lamina that separates the epithelium from other tissue.
