Document Summary

Regions and organization of the cns: spinal cord. The spinal cord consists of a central cavity surrounded by grey matter, with external white mat- ter being composed of myelinated fibre tracts: adult brain regions. The brain has a similar pattern as the spinal cord, however consists of additional areas of grey matter in the brain. The brain consists of cerebral hemispheres and cerebellum, with the cortex (outer grey matter) disappearing into the brain stem. Throughout the brain, scattered grey mat- ter nuclei surround the white matter. Complexity of wiring rather than size is what matters: cerebral hemispheres, diencephalon (thalamus, hypothalamus, epithalamus, brain stem (midbrain, pons, and medulla, cerebellum. The brain ventricles are continuous with one another and with the central cavity of the spinal cord. All ventricles are connected to one another and to the central canal of the spinal cord. The chambers are filled with cerebrospinal fluid (csf) and lined with ependymal cells (neuroglia).
