The process whose specific outcome is the progression of the larva over time, from its formation to the mature structure. This begins with the newly hatched first-instar larva, through its maturation to the end of the last larval stage. An example of this process is found in Drosophila melanogaster.

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

The process whose specific outcome is the progression of the ventral cord over time, from its formation to the mature structure. The ventral cord is one of the distinguishing traits of the central nervous system of all arthropods (such as insects, crustaceans and arachnids) as well as many other invertebrates, such as the annelid worms.

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.

The process whose specific outcome is the progression of the adult fat body over time, from its formation to the mature structure. Larval fat body cells that remain at eclosion degenerate in the first 2 to 4 days of adult life, leaving behind the smaller cells of the adult fat body.

The eversion (turning inside out) of imaginal discs from their peripodial sacs, resulting in movement of the epithelium to the outside of the larval epidermis.

The periodic shedding of part or all of a chitin-based cuticle, which is then replaced by a new cuticle. An example of this is found in Drosophila melanogaster.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.

The controlled breakdown of the basement membrane in the context of a normal process such as imaginal disc eversion.

Growth of epithelial tubes that originate from pits in an open tracheal system and grow towards each other to meet and form a continuous open tube called the dorsal trunk. The dorsal trunk extends from the anterior spiracle to the posterior spiracle of the larva and forms the main airway of the insect tracheal system.

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

The series of events that restore integrity to a damaged tissue, following an injury.

The regrowth of lost or destroyed tissues.

The regrowth of lost or destroyed tissues.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a cell-cell junction. A cell-cell junction is a specialized region of connection between two cells.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the basement membrane.

The collection of motor neuron axons into a bundle of rods, known as a fascicle.

The process that gives rise to the embryonic heart tube. This process pertains to the initial formation of a structure from unspecified parts. The embryonic heart tube is an epithelial tube that will give rise to the mature heart.

A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.

An extracellular matrix consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that provides not only essential physical scaffolding for the cellular constituents but can also initiate crucial biochemical and biomechanical cues required for tissue morphogenesis, differentiation and homeostasis. The components are secreted by cells in the vicinity and form a sheet underlying or overlying cells such as endothelial and epithelial cells.
