What are the main parts of the brain and their general functions?
You can refer to Chapter 9 in your textbook to view drawings of the major parts of the brain & their locations from pages 236 to 243. a. cerebrum In humans, the cerebrum is the largest portion of the brain. It is involved in conscious motor functions, reception & analysis of sensory input, & conscious thoughts such as judgment, memory & reasoning. It is separated into a right & a left hemisphere. Each hemisphere has 5 lobes, 4 of which are named according to the skull bone they lie under: frontal, parietal, occipital, temporal. The fifth lobe of each hemisphere is called the insula (“island”), which is folded toward the inside & covered by sections of the frontal, parietal, & temporal lobes. The outer approximately 1/4 inch of the cerebrum is the cerebral cortex, which contains nerve cell bodies. Each region of the cerebrum has very specific functions. Figure 9.24 of the textbook points out the specific functions of several parts of the cerebrum. b. diencephalon The diencephalon includ
