Summary Introduction

Introduction:

Nervous system contains microglial cells, blood brain barrier, macrophages, and some bony structures, that act as a barrier against the invading microorganism.

The membrane which controls any substance to enter in the central nervous system from blood stream is termed as the blood brain barrier. The membrane forms a physical barrier between central nervous system and local blood vessels against microorganism and other substances but heavy metals, some drugs, and alcohol can cross it.
