What Wraps Your Spinal Cord Inside the Bony Canal?

READ THE IMAGE

What the illustration shows

Anatomical teaching poster titled What wraps the spinal cord? A cross-cut bony canal surrounds yellow epidural fat, a thick white dura, a closely underlying arachnoid, a blue cerebrospinal-fluid space with delicate strands, and thin pia on the spinal cord. Leaders name each layer. A lower enlargement repeats the outside-to-inside order: bone, epidural fat, dura, arachnoid, CSF space, pia and cord. The takeaway states that CSF surrounds the cord inside the arachnoid. Proportions and textures are schematic, not a surgical map. Gold AllHumanBody.com branding and its complete slogan appear at the bottom.

How to interpret this poster

• Schematic spinal, not cranial, layering; no exact vertebral level, membrane thickness or tract map.
• No wide normal subdural fluid compartment or CSF outside the dura.
• No needle, injection procedure, puncture guidance, meningitis diagnosis or treatment.
• AI-assisted educational illustration; not physician certification, microscopy, a diagnosis or individualized medical advice.
• Fine annotations need enlargement; the full description provides an accessible text alternative.
• Display the full uncropped illustration; do not trim titles, legends or boundary annotations.
