  1. Major divisions
    1. Frontal Lobe
    2. Parietal Lobe
    3. Occipital Lobe
    4. Temporal Lobe
  2. Anatomical landmarks (divide the cerebral lobes into further identifiable regions)
    1. Brain Gyri
    2. Brain sulci and Brain Fissures
  3. Internal Capsule
    1. Bundles of axons coursing between the cerebral cortex and the Brainstem (one for each hemisphere)
    2. Composed of three parts: Anterior limb, posterior limb, and genu
    3. Vascular supply via the Anterior Circulation
      1. Supplied by small vessels (anterior Choroidal artery, medial striate artery, lateral striate artery)
      2. Hemorrhage may occur in the supplying vessels with Severe Hypertension
      3. CVA in this region (despite small distribution) may result in significant neurologic deficits
