Nervous system
Looks like
A very thin, transparent membrane clinging to every fold of the brain and spinal cord surface.
What it does
Carries fine blood vessels into the brain tissue.
Keeping it well
Inflamed with the other membranes in meningitis; vaccines against meningococcus, pneumococcus and Hib prevent the main causes.
