It acts as an embryonic organiser and plays an essential role both in the generation of specific neuronal subtypes along the dorsoventral axis of the brain and spinal cord and in the guidance of axons giger and kolodkin 2001.
Biology a specialized glial structure integral to the developing nervous system of vertebrate organisms origin floor plate.
Located on the ventral midline of the embryonic neural tube the floor plate is a specialized glial structure that spans the anteroposterior axis from the midbrain to the tail regions it has been shown that the floor plate is conserved among vertebrates such as zebrafish and mice with homologous.
Plate tectonics theory dealing with the dynamics of earth s outer shell that revolutionized earth sciences by providing a uniform context for understanding mountain building processes volcanoes and earthquakes as well as the evolution of earth s surface and reconstructing its past continents and oceans.
