Brain regions overview — main parts?
Cerebrum, diencephalon, brainstem, cerebellum.
Gray vs white matter — difference?
Gray: neuron cell bodies; white: myelinated axons.
Brain protection structures — components?
Skull, meninges, CSF, blood-brain barrier.
Cranial meninges layers — order?
Dura mater, arachnoid mater, pia mater.
Meningitis — inflammation of?
Meninges surrounding the brain and spinal cord.
Encephalitis — inflammation of?
Brain tissue itself.
Brain ventricles — number?
Four: lateral, third, and fourth ventricles.
CSF — functions?
Cushions brain, removes waste, transports nutrients.
Cerebrum — primary functions?
Higher thinking, sensation, voluntary movement.
Gyri — definition?
Ridges on brain surface.
Sulci — role?
Shallow grooves separating gyri.
Fissures — difference from sulci?
Deeper grooves between brain regions.
Lateral ventricles — location?
In each cerebral hemisphere.
Cerebral cortex — composition?
Gray matter covering cerebrum.
