PS275 Lecture Notes - Lecture 9: Meninges, Parietal Lobe, Central Sulcus
Document Summary
Structure and funtion of the human brain box. Inside the skull the brain is enveloped within three layers of non neural tissue, membranes referred to as meninges. Viewed from the top the brain is divided by a midline fissure into two mirror image cerebral hemispheres together constituting most of the cerebrum. basal ganglia and limbic system. The cerebrum is the thinking centre of the brain, which includes the cortex and sub cortex structures such as the. The major connections between the two hemispheres is a band of nerve fibres called the corpus callosum. The upper side and some of the lower surfaces of the hemispheres form the cerebral cortex. The corxt consist of 6 layers of tiglhy packed neuron cell bodies with many short unsheathed interconnecting processes areas called lobes. These neurons estimated to # 10-15 billion make up a thin outer covering the so called grey matter of the brain.
