Summary Introduction
Introduction:
Blood-brain barrier is a semipermeable barrier that separates the circulating blood from the extracellular fluid and brain in the central nervous system. It is formed by the endothelial cells of the capillary wall. This barrier restricts the movement of some molecules while facilitating the movements of other molecules.
