Ingression (other)
Ingression may refer to: * Ingression (biology) * Ingression coast See also * Ingress (other) * Ingressive sound In phonetics, ingressive sounds are sounds by which the airstream flows inward through the mouth or nose. The three types of ingressive sounds are lingual ingressive or velaric ingressive (from the tongue and the velum), glottalic ingressive ...

Ingression (biology)
Ingression is one of the many changes in the location or relative position of cells that takes place during the gastrulation stage of embryonic development. It produces an animal's mesenchymal cells at the onset of gastrulation. During the epithelial–mesenchymal transition (EMT), the primary mesenchyme cells (PMCs) detach from the epithelium and become internalized mesenchyme cells that can migrate freely. While the mechanisms of ingression are not fully understood, studies using the sea urchin as a model organism have begun to shed light on this developmental process, and will be the focus here. There are three main changes that must occur within a cell to enable the process of ingression. The ingressing PMCs must first alter their affinity for the neighboring epithelial cells that will remain in the vegetal pole (vertebrate PMCs ingress from the primitive streak). During this time, these cells must lose their affinity for the hyaline layer to which their apical surface is att ...

Ingression Coast
An ingression coast or depressed coast is a generally level coastline that is shaped by the penetration of the sea as a result of crustal movements or a rise in the sea level. Such coasts are characterised by a subaerially formed relief that has previously experienced little deformation by littoral (tidal) processes, because the sea level, which had fallen by more than 100 metres during the last glacial period, did not reach its current level until about 6,000 years ago. Depending on the geomorphological shaping of the flooded landform – e.g. glacially or fluvially formed relief – various types of ingression coast emerge, such as rias, skerry and fjard coasts as well as förde and bodden coasts.Leser, Hartmut, ed.
