A cell cycle process that sets the alignment of mitotic spindle relative to other cellular structures.

The actin-mediated process that results in the contraction of the apical end of a polarized columnar epithelial cell, contributing to the process of gastrulation.

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.

The migration of individual cells within the blastocyst to help establish the multi-layered body plan of the organism (gastrulation). For example, the migration of cells from the surface to the interior of the embryo (ingression).

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

The attachment of a neuron to another cell via adhesion molecules.

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

The process in which the anatomical structures derived from an imaginal disc are generated and organized. The imaginal discs are epithelial infoldings in the larvae of holometabolous insects that develop into adult appendages (legs, antennae, wings, etc.) during metamorphosis from larval to adult form.

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

The behavior of a male, for the purpose of attracting a sexual partner. An example of this process is found in Drosophila melanogaster.

The behavior of a female, for the purpose of attracting a sexual partner.

Any process in which the axon of a neuron is insulated, and that insulation maintained, thereby preventing dispersion of the electrical signal.

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 assembly of a septate junction, an intercellular junction found in invertebrate epithelia that is characterized by a ladder like appearance in electron micrographs and thought to provide structural strength and to provide a barrier to diffusion of solutes through the intercellular space.

A developmental process, independent of morphogenetic (shape) change, that is required for a nerve to attain its fully functional state.

Formation of a multilayered, melanized sheath of cells around a foreign invader.

Ensuring that an epithelial tube in an open tracheal system is of the correct length and diameter. Tracheal tubes undergo highly regulated tube-size increases during development, expanding up to 40 times their initial size by the end of larval life. Tube size appears to be controlled by regulation of apical membrane expansion and secretion, rather than by changes in cell number, size or shape.

Any process that modulates the frequency, rate or extent of the willingness or readiness of a female to receive male advances.

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.

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

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a synapse, the junction between a neuron and a target (neuron, muscle, or secretory cell).

Establishment of the glial barrier between the blood and the brain. The glial cells in the brain are packed tightly together preventing the passage of most molecules from the blood into the brain. Only lipid soluble molecules or those that are actively transported can pass through the blood-brain barrier.

The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules that contributes to the shaping of the heart.

The chemotaxis process that directs the migration of a photoreceptor cell axon growth cone to its target in the optic lobe in response to a combination of attractive and repulsive cues.

The attachment of one cell to another cell via adhesion molecules.

Any process that modulates the frequency, rate or extent of dendrite morphogenesis.

Any process that activates or increases the frequency, rate or extent of dendrite morphogenesis.

Any process that activates or increases the frequency, rate or extent of dendrite morphogenesis.

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

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

Any process that modulates the frequency, rate or extent of dendrite extension.

Any process that modulates the frequency, rate or extent of dendrite extension.

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

An adherens junction which connects a cell to another cell.

The portion of the plasma membrane at the lateral side of the cell. In epithelial cells, lateral plasma membranes are on the sides of cells which lie at the interface of adjacent cells.

The repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.

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

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

A cell-cell junction that forms a continuous band around each cell in an epithelium; within the septate junction the membranes of adjacent cells maintain a constant distance of approximately 15 nm; found in arthropods.

A septate junction in which regular arrays of electron-dense septae span the intermembrane space.

Thin, stiff, actin-based protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal or dendritic growth cone, or a dendritic shaft.

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 portion of the plasma membrane surrounding an axon; it is a specialized trilaminar random mosaic of protein molecules floating within a fluid matrix of highly mobile phospholipid molecules, 7-8 nm in thickness.

The portion of the plasma membrane surrounding a dendrite.

The plasma membrane of a neuron cell body - excludes the plasma membrane of cell projections such as axons and dendrites.

The migrating motile tip of a growing nerve cell axon.
