Anatomy and Physiology Review Glial Cells
Glial cells – two main classes: Microglia and Macroglia
Microglia cells respond to infections or trauma in CNS.
Macroglia Cells are divided into four subsets:
Astroglia (star-shaped) cells provide physical support for neurons, regulate chemical environment, nourish.
Oligodendrocyte and Schwann cells – form the myelin sheath.
Ependymal cells for lining of ventricles of the spinal cord. Also part of blood-brain barrier.
