Detailed explanation-1: -The blood-brain barrier is the barrier between the cerebral capillary blood and the interstitial fluid of the brain. It is made up of capillary endothelial cells and basement membrane, neuroglial membrane, and glial podocytes, i.e., projections of astrocytes.

Detailed explanation-2: -Astrocytes are the glial cells that help form the blood-brain barrier. The blood-brain barrier is formed from vascular endothelial cells that create the microvasculature in the brain and astrocytes.

Detailed explanation-3: -The BBB is formed by microvascular endothelial cells lining the cerebral capillaries penetrating the brain and spinal cord of most mammals and other organisms with a well-developed CNS [3].
