Brain stem
Inferior stalk-like portion connecting to spinal cord

Sulci
Central sulcus
Large groove. Runs down midpoint at top brain
Central sulcus separates:
Frontal and parietal lobe
Pre-central gyrus
Groove immediately anterior to central sulcus
Part of frontal lobe
Post-central gyrus
Groove immediately posterior to central sulcus
Part of parietal lobe
Lateral sulcus
Large groove that runs horizontally from front of brain
Lateral sulcus separates:
Frontal and parietal from temporal lobe
Frontal lobe location
Anterior of central sulcus
Superior to lateral sulcus
