How Meningitis Can Affect the Brain and Spinal Cord
Meningitis is inflammation of coverings around the brain and spinal cord. In the bacterial example shown, bacteria in the subarachnoid space can trigger inflammation that may affect nearby neural tissue.

What the illustration shows
Gold title: How Meningitis Can Affect the Brain and Spinal Cord. A brain and upper spinal cord locator connects a cranial sample to a large layered cutaway. From outside inward, labeled ivory dura and arachnoid sit above a cyan subarachnoid space containing schematic gold rod bacteria and violet inflammatory cells. A thin pink pia follows the peach neural surface beneath. Labels identify the CSF space, pia and neural tissue. A matching bacteria and inflammatory-cell legend accompanies text explaining inflammation in this space and that not every brain cell is infected. A visible qualifier reads Bacterial example; other causes differ, followed by Local cranial example, simplified, not to scale. Gold AllHumanBody.com branding and full slogan appear below.
How to interpret this poster
- Bacterial example only, not every cause or infection of every brain cell. No symptom triage, reassurance, test or treatment; organisms/cells not to scale or strain identification.
- AI-assisted educational illustration; not physician certification, a diagnosis or individualized medical advice.
- Fine annotations require enlargement; preserve the full uncropped illustration and its qualifiers.
