Cerebrospinal
Pertaining to the brain and the spinal cord
Combining Form for Meninges
Meningo
Meningio
Meninges

Combining Form for nerve
Neuro

Not necessarily a tumor
Collection of blood in brain
Options of brain hematoma
Epidural
Subdural
Intracerebral
Cerebrospinal Fluid
Liquid that brain and spinal cord are contained in
Sciata

Sciatic Nerves
Large nerve that runs from the low back down the back of the legs
Ventricles
Where the CSF is produced and stored
Hydrocephalus
Too much CSF in brain
Common in dwarfism
Also called “water on the brain”
Why does hydrocephalus happen?
CSF is not being reabsorbed as often as it is produced
Lumbar Puncture
Spinal tap
Done to diagnose MS or meningitis
Glioma
Tumor of neuroglial cell
Neuroglial cells
Support neurons
ALS

Degeneration of motor neurons
MS
Multiple sclerosis
Demyelination disease
Parkinson’s Disease
Degeneration of region of brain
What part of the brain degenerates in people with Parkinson’s disease?
Substantia Nigra
CVA
Cerebrovascular accident
Stroke (usually thrombotic)
