Document Summary
Divisions of the brain: cerebrum (brown, anatomy, 2 hemispheres (r & l, hills (gyri) and valleys (sulci) - allow for more surface area, giving us more. Shaped like a wrinkled boxer"s glove computational power: function, voluntary motor function. Language and learning: cerebral gray matter, cerebral cortex. Superficial layer containing cell bodies: cerebral white matter, contains fibres connecting cortical areas to each other, deep gray matter, basal ganglia - large masses of cell bodies, lobes: Lateral sulcus: temporal and frontal, parieto-occipital sulcus, parietal and occipital. Frontal lobes: cerebral gyri, elevations of the cerebrum. Involved in sensory and motor processing: thalamus, relay station to cerebral cortex, all sensory input enters thalamus, carries motor from cerebellum to cortex, hypothalamus. Implicated in parkinson"s: pons, pathway for connections, cerebral cortex and cerebellum. Spinal cord to cerebellum: medulla, begins as foramen magnum, resembles spinal cord, contains cardiac and respiratory centres, contains the pyramids (motor tracts, decussation of periods - information crosses over.
