Can there be two types of cells present inside grey matter or at a particular location?
Like marcoglial and microglial cells both are present in grey matter?
Won't both of them act contrary to each other?
Dear student,
The grey matter mainly consists of neuronal cell bodies and unmyelinated axons. The grey matter contains the glial cells (astroglia and oligodendrocytes ) . All the glial cells apart from microglial cells ,i.e, astrocytes, oligodendrocytes or glioblasts , are macroglial cells.
Microglia have mesodermal origin. They have branched cytoplasmic processes and they function as macrophages of the CNS and thus play the phagocytic role.
On the other hand, macroglial cells have ectodermal (neural) origin. These cells acts as supporting cells within the central nervous system and help in recovery during inflammation or injury. Glioblasts are actually the stem cells which can differentiate further into macroglial cells.
Regards.
