The spreading of the amnioserosa from its compressed state to cover the whole of the dorsal surface. Initiating in the thorax and spreading posteriorly, it is accompanied by the transition from a parasegmental to segmental division of the embryo.

The process whose specific outcome is the progression of the ectoderm over time, from its formation to the mature structure. In animal embryos, the ectoderm is the outer germ layer of the embryo, formed during gastrulation.

The process whose specific outcome is the progression of the central nervous system over time, from its formation to the mature structure. The central nervous system is the core nervous system that serves an integrating and coordinating function. In vertebrates it consists of the brain and spinal cord. In those invertebrates with a central nervous system it typically consists of a brain, cerebral ganglia and a nerve cord.

The orderly movement of epithelial cells during development of an open tracheal system. An example of this is found in Drosophila melanogaster.

The orderly movement of epithelial cells during development of an open tracheal system. An example of this is found in Drosophila melanogaster.

The process whose specific outcome is the progression of the muscle over time, from its formation to the mature structure. The muscle is an organ consisting of a tissue made up of various elongated cells that are specialized to contract and thus to produce movement and mechanical work.

The process whose specific outcome is the progression of the somatic muscle over time, from its formation to the mature structure. Somatic muscles are striated muscle structures that connect to the exoskeleton or cuticle.

The process that mediates the transfer of information from the cells of a muscle to those of its intended target, thereby identifying the target site.

The chemical reactions and pathways involving pigment, any general or particular coloring matter in living organisms, e.g. melanin.

Any process that activates or increases the rate or extent of cell proliferation.

Any process that stops, prevents, or reduces the frequency, rate or extent of MAP kinase activity.

Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that stops, prevents, or reduces the frequency, rate or extent of ovulation, the release of a mature ovum/oocyte from an ovary.

Any process that stops, prevents or reduces the frequency, rate or extent of oocyte maturation.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

Cytoplasm situated near, or occurring around, the nucleus.
