Document Summary
The brain: cerebrum: two cerebral hemispheres, cerebellum: two cerebellar hemispheres, diencephalon: hypothalamus, thalamus, epithalamus, brain stem: midbrain, pons, medulla oblongata. The brain: cerebellum and cerebral hemispheres, cortex: outer layer of gray matter, white matter is deep to cortex, nuclei: gray matter deep within white matter. Ventricles: lateral ventricles , interventricular foramen , cerebral aqueduct: passes through midbrain , fourth ventricle: bordered by pons and medulla oblongata and cerebellum , median and lateral apertures: leads to subarachnoid space or, central canal. Third ventricle: in the diencephalon : cerebral cortex: superficial layer of gray matter, cerebral white matter: fiber tracts, basal nuclei, paired masses of gray matter, deep w/in cerebral white matter. Cerebrum: cerebral hemispheres, supported on brainstem: surrounds diencephalon, connected by corpus callosum (bundles of transverse white fibers, gyri elevated ridges of tissue, sulci shallow grooves between gyri, fissure deeper grooves separating larger regions of brain. Cerebrum: central sulcus separates frontal and parietal lobes.
