Your brain and spinal cord are covered by a series of tough membranes called meninges, which protect these organs from rubbing against the bones of the skull and spine.
For further protection, the brain and spinal cord "float" in a sea of cerebrospinal fluid within the skull and spine. This cushioning fluid is produced by the choroid plexus tissue, which is located within the brain, and flows through a series of cavities (ventricles) out of the brain and down along the spinal cord. The cerebrospinal fluid is kept separate from the blood supply by the blood-brain barrier.
As you can see, your brain is a complex, highly organized organ that governs everything you do. Now that you are familiar with the anatomy of the brain, keep reading for more articles on how it works.
