II. Definitions

  1. Cerebrum (Telencephalon)
    1. Largest portion of the Central Nervous System, the Cerebrum contains the cerebral cortex (two hemispheres)
    2. The Cerebrum also includes the subcortical structures (hippocampus, Basal Ganglia, amygdala and the Olfactory Bulb)

III. Anatomy

  1. Anatomical landmarks (divide the cerebral lobes into further identifiable regions)
    1. Brain Gyri
    2. Brain sulci and Brain Fissures
  2. Brodmann Areas
    1. Established brain regions by histology in the early 1900s by German researcher
  3. Brain Lobes
    1. Frontal Lobe
      1. Anterior to the central sulcus of Rolando (where the Frontal Lobe meets the Parietal Lobe)
    2. Parietal Lobe
    3. Occipital Lobe
    4. Temporal Lobe
      1. Inferior to the Lateral Fissue of Sylvia (where the Temporal Lobe meets the Frontal Lobe and Parietal Lobe)
  4. 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

Ontology: Internal capsule of brain (C0152341)

Definition (FMA) Internal capsule is an organ subdivision of the telencephalon which is made up primarily of myelinated axonal neural tissue (white matter). The internal capsule is a major set of fiber bundles lateral to the thalamus and caudate nucleus and medial to the putamen and globus pallidus. It projects dorsally to the white matter underlying the cerebral cortex.
Definition (NCI) White matter pathway, flanked by nuclear masses, consisting of both afferent and efferent fibers projecting between the cerebral cortex and the brainstem. It consists of three distinct parts: the anterior limb, posterior limb, and genu. (MeSH)
Definition (MSH) WHITE MATTER pathway, flanked by nuclear masses, consisting of both afferent and efferent fibers projecting between the WHITE MATTER and the BRAINSTEM. It consists of three distinct parts: an anterior limb, posterior limb, and genu.

Ontology: Cerebrum (C0242202)

Definition (CSP) part of the brain derived from the embryonic telencephalon and consisting of the cortex and white matter of the cerebral hemispheres, the basal ganglia, and certain other basal structures which are a part of the rhinencephalon.
Definition (MSH) Derived from TELENCEPHALON, cerebrum is composed of a right and a left hemisphere. Each contains an outer cerebral cortex and a subcortical basal ganglia.
