E Correct answer
Explanation

Blood brain barrier is formed by specific nueroglial cells called astrocytes. These astrocytes are of two types-fibrous astrocytes and protoplasmic astrocytes. The fibres of these astrocytes form a network with capillaries of blood vessels that supply blood to brain. This network of fibres forms a barrier between blood medium and brain tissue for the purpose of maintaining homeostasis.
