Class Summary - Today we took our Tuesday textbook quiz. Then we started talking about the brain. We discussed how often the brain is talked about in separate parts; the cerebrum, cerebellum, brain stem and diencephalon. We discussed the cerebrum, the largest part of the brain, mostly today. The cerebrum has two hemispheres connected by the corpus collosum. We talked about the gyri (ridges) and sulci (grooves) in the brain. Today we also discussed the lobes of the cerebrum which are separated by main sulci. The lobes are the frontal lobe, parietal lobes, occipital lobes, temporal lobes and the insula lobe. We also discussed what main functions happen in each of these lobes. Then we discussed the cerebral cortex. The cerebral cortex is all gray matter than controls voluntary movement and a lot of sensory communication in the body. We discussed the Broca's area (motor speech) and the Wernicke's area (interpreting speech). We also discussed the basal nuclei. This part of the white matter makes sure the correct body muscles are activated at the right time. Parkinson's disease and Huntington's Disease are believed to be disorders of the basal nuclei areas.
Homework - Quiz on Lobes and Brain Divisions Tomorrow, (Correcting Homework Packet Tomorrow)
Objectives - Students will describe the major parts of the brain and the lobes of the cerebral cortex. Students will describe the major parts of the brain and state functions for each structure.
