Description
Blood-brain barrier. Illustration of the haematoencephalic barrier between the blood flow and the central nervous system. This system regulates the environment (homeostasis) in the brain by separating it from the blood. Both the endothelial cells (red) that line the capillaries and the surrounding astrocytes (pink) are essential components of this barrier. The blood-brain barrier stops harmful chemicals and bacteria from reaching the brain. The brain cell types shown here are neurons (blue) and oligodendrocytes (orange). Also shown are the axons, synapses, myelin sheaths and nodes of Ranvier. Viruses and special types of drugs are able to pass the blood-brain barrier. For this artwork with labels, see image C030/3031.
