causes impulses to travel faster

• Central nervous system-brain is protected by the skull• The 3 main parts

• Cerebrum-the outside is called the cerebral cortex & controls the highest functions of the brain-center of thought & intelligence

• Cerebellum-regulates & co-ordinates body movements-balance & smooth movement of the muscles

• Brainstem-connects the cerebrum to the spinal cord-it controls vital functioning of the organs such as breathing, heart rate, blood vessel size, swallowing, coughing & vomiting
