The Brain and the Nervous System

Central Nervous System The central nervous system (CNS)

consists of the brain and the spinal cord

The Peripheral Nervous System

The Peripheral Nervous System (PNS) consists of a system of nerve cells that transmit information to and from the control center.

The Central Nervous System and Peripheral Nervous System

These two systems work together to make sure important information gets to your brain to be processed and interpreted and to make sure that the correct response is generated.

Draw and label the components of the Central Nervous System on to your Graphic Organizer

The Brain Stem Notice that the brain stem consists

of three parts: the midbrain, the pons and the medulla oblongata.

The Spinal Cord Be aware that the spinal cord

connects the brain to the body and controls for input to the control center and output to the rest of the body. Together, the brain and the spinal cord form the central nervous system.

Analysis Questions How do the central nervous system and the

peripheral nervous system work together to control the body?

A man slips, falls and bangs the back of his head on the tile floor. The doctor tells him he has some minor swelling in the occipital lobe of his cerebrum. His doctor sends him home to rest and tells him that if there are any changes, he should come back in. What changes would be worrisome, given the area that was injured?

Brain Lobe Functions Working with a team of four, research

the areas of the brain responsible for the actions, emotions, personality traits, or functions that are listed on the board. Each team member is responsible for researching four or five items from the list and reporting his/her findings to the group. Work together to divide the work.

Analysis Questions 1. Why is the story of Phineas Gage considered so

extraordinary? What does his story teach us about the brain?

2. New research is using functional MRI (magnetic resonance imaging), a scan of the brain that shows specific areas that are activated during certain tasks, as a lie detector test. Explain which area(s) of the brain you think might light up to show that you are telling a lie or telling the truth. Explain your reasoning.

3. Ten-year-old Alex Fuentes damaged his occipital lobe and his cerebellum in a car accident. Explain to his parents some of the possible effects of this injury.
