Document Summary
The nervous system is divided into two major parts: central nervous system, peripheral nervous system. Central nervous system- is composed of the brain and the spinal cord. Cerebral cortex- from the latin word bark , where most actual information processing takes place. Gray because nerves in this area lack the insulation that makes most part of the brain appear white. The cortex of the cerebrum receives and am=analyses impulses. Each hemisphere is divided into the respective lobes by folds in the cerebral cortex called fissures or sulci. Fissure of rolando (central sulcus)- separates the frontal lobe from the parietal lobe. Sylvian fissure- separates the frontal lobe from the temporal lobe. Parieto- occipital fissure- separates the parietal lobe from the occipital lobe. Speech: speaking and writing (broca"s area- is located in the left frontal. It is the motor (expressive) speech center- enables a person to speak clearly and make gestures. ) Sense of touch, pain, temperature (sensory strip)
