Document Summary
Brain the encephalon developed from the anterior part of the embryonic neural tube, part of the. Cerebrospinal fluid clear solution of sodium chloride and other salts that cushions the brain and may play a role in removing metabolic waste. Csf fills the ventricles inside the brain and circulates around the brain beneath the arachnoid layer in the subarachnoid space. Cerebral cortex outer layer of gray matter on the surface of the cerebral hemispheres and composed of neurons and their synaptic connections that form 6 sublayers. Gyri (s. gyrus) bumps in the neocortex produced by folding. Sulci (pl. sulcus) cleft in the cortex produced by folding. Longitudinal fissure - deep clefts that divides the brain"s two hemisphere. Lateral fissure - deep cleft in the cortical surface of the brain that separates the temporal and parietal lobes. Corpus callosum commissure (fiber system) that connects homotopic areas in the two hemispheres: damage to the corpus callosum causes split-brain (hemispheres are isolated)
