Neuroanatomy review

>Forebrain/Prosencephalon
Gray matter
├Telencephalon
│├Cerebral cortex
│└Basal telencephalon
└Diencephalon
 ├Thalamus(gateway)
 └Hypotalamus(control ANS)
White matter
├Corpus callosum
├Cortical white matter
└Internal capsule
*Sensory→Thalamus→Internal capsule→Cerebral cortex
*Cerebral cortex→corticospinal tract→spinal cord

>Midbrain/Mesencephalon
┌Tectum(roof)
│├Superior colliculus(eye)
│└Inferior colliculus(ear)
├Cerebral aqueduct(3rd ventrical)
└Tagmentum

>Hindbrain/Rhombencephalon
┌Cerebellum(spacial info)
├Pons(synapse from cerebral cortex to cerebellum)
└Medulla oblongata
*4th ventricle~CSF-filled tube

>Spine
Gray matter
├Dorsal horn(←dorsal root)
├Intermediate zone
└Ventral horn(←ventral root)

>lobes
⇔temporal
←frontal
↑parietal
→occipital

>Meninges
├Dura mater
├Arachnoid membrane
└Pia mater
