composed of a fine tetwork of blood vessels and neural tissue. Highly susceptible to hemorrhage in the premature infant
Elevated or convoluted fold on the surface of the cerebral hemispheres separated by sulci or fissures
Diencephalon structure located just inferior to the thalmus at the base of the brain. composed of several different areas, even though it is just the size of a pea. communicates directly with the pituitary gland
dep groove or indentation separating the right and left cerebral hemispheres. contains the falx cerebri
Cerebrospinal fluid filled cavities within each cerebral hemisphere. Lie just below the corpus callosum and are separated from each other by the septum pellucidum, a thin partition. each lateral ventricle is divided segmentally into a frontal horn, body, occipital horn, and temporal horn
Extends inferiorly from the pons to form the inferior portion of the brainstem that projects out of the skull through the foramen magnum (a large opening in the posterion protion of the occipital bone of the skull_ and connects to the spinal cord
Superioir portion of the brainstem situated where the crebellum and pons unite.
Cerebral brain lobe located posteriorly inthe brain. involved with vision.
cerbral brain lobe located posterior to the frontal cortex. contains the body's sensory receptors. which interpret the impulses that allow one to recognize sensations such as pain, cold or a light touch
innermost layer of three meningeal protective and supportive tissues surrounding the brain and spinal cord. Adjacent to the brain and spinal cord surfaces
