The Brain & Its Regions
Start with the big picture
The cerebrum forms the largest part of the brain, with hemispheres connected by the corpus callosum and lobes associated with specialized cortical functions. The topic also surveys the basal ganglia’s role in movement modulation and the limbic system’s links to memory, emotion, and motivation. It distinguishes the thalamus, hypothalamus, and other diencephalic structures, then follows the brainstem through its midbrain, pons, and medulla divisions. The cerebellum is introduced as a structure that fine-tunes movement and balance. Additional sections map the ventricular CSF pathway, meninges and dural folds, cerebral circulation and venous drainage, Brodmann areas, internal capsule, reticular activating system, and major brain fiber types.
What you'll learn
- Identify the major cerebral lobes and associate key cortical areas with their functions.

- Distinguish the divisions of the brainstem and summarize their principal functions.
- Trace the CSF pathway and identify the meninges and major dural folds.
- Recognize major features of cerebral circulation, venous drainage, and brain fiber organization.
