Document Summary

Not shown in this image is the diencephalon, which consists of the thalamus and hypothalamus: the brain stem controls basic functions such as heart rate and respiration. Brain stem made up of pons, midbrain and medulla oblongata (continuous with spinal cord): at the back region (posterior) of the brain just above the brain stem is the cerebellum, which is responsible for coordinated movement. There are many bumps (gyri) and dips (sulci), which increase surface area of brain. Each hemisphere can be divided into these 4 lobes. The frontal lobe contains the primary motor cortex, which processes input from skeletal muscles. The premotor and prefrontal cortexes integrate movement information with other sensory inputs to generate perception. The parietal lobe contains the primary somatosensory cortex, which receives input from the major sense organs (skin, musculoskeletal system, and taste buds). The association areas integrate sensory information with other association areas of the cortex to form meaningful perceptions.
