Document Summary
Receives information from the eyes, ears, skin all the senses except for smell and sends those signals up to the cerebral cortex for processing: also transmits replies from the cortex to the medulla and cerebellum. Relays touch signals to the sensory cortex, visual info to the visual cortex, etc. The brain has two halves a left hemisphere and a right hemisphere and they are connected by the corpus callosum: corpus callosum = bundle of nerve fibers that send messages between the two hemispheres. Hemispheres are covered by the cerebral cortex: cerebral cortex. Allows us to coordinate movement, perceive the environment, carry out higher mental functions like language, problem solving, and planning. Hemispheres are divided into lobes, each separated by prominent fissures or folds. Frontal lobes: behind the forehead, speaking, muscle movement, planning, judgment. Parietal lobes: at the top rear of the brain, receives sensory input for touch and body position. Occipital lobes: back of the head.
