Glial scarA glial scar formation (gliosis) is a reactive cellular process involving astrogliosis that occurs after injury to the central nervous system. As with scarring in other organs and tissues, the glial scar is the body's mechanism to protect and begin the healing process in the nervous system. In the context of neurodegeneration, formation of the glial scar has been shown to have both beneficial and detrimental effects.
GlioseGliosis is a nonspecific reactive change of glial cells in response to damage to the central nervous system (CNS). In most cases, gliosis involves the proliferation or hypertrophy of several different types of glial cells, including astrocytes, microglia, and oligodendrocytes. In its most extreme form, the proliferation associated with gliosis leads to the formation of a glial scar. The process of gliosis involves a series of cellular and molecular events that occur over several days.
AbdomenL’abdomen (du latin, de même sens) est une partie du corps humain ou du corps d'un animal. Chez l'être humain, il est également appelé ventre. thumb|Abdomen masculin. thumb|Repères de la face antérieure du tronc. Chez l'être humain, l'abdomen est la région du corps située entre le thorax en haut et le petit bassin en bas, contenant la plus grande partie des organes digestifs. Schématiquement, on peut diviser l'abdomen en deux parties : la cavité abdominale, en avant, contenant la plupart des organes du système digestif entourés du péritoine.
