**FIRST SLIDE:** J: Hello I'm Jerry, today on Body System News we will be exploring the nervous system. First we will be talking about the central nervous system, which is the brain and spinal cord. I'm going to send you over to Meghan and Jack who are in the brain. M: Right Now we are in the Central Nervous System J: In the Central Nervous System, there are two parts, the brain and the spinal cord.
 * SECOND SLIDE:**

M: Thanks, Jerry. In the brain right now, this person is thinking about being hungry. The brain controls most functions of the body, including your behavior. The brain receives and distributes messages for the rest of the body using the spinal cord. There are three main parts of the brain, the cerebrum, the cerebellum, and the brain stem.  J: The cerebrum is a very large part of the brain and controls the five senses. M: That's right and the cerebellum controls voluntary actions such as talking and eating. J: The brain stem is the third part of the central nervous system. M: Also known as the medulla, the brain stem carries out invouluntary actions, like coughing or sneezing. Back to you Jerry! J: Thank you Jack and Meghan for your wonderful report. Now I will send you viewers to Mary and John who are in the spinal cord, the final part of the central nervous system. M: Thanks Jerry! Well, the spinal cord is a thick column of nervous tissue. It is the bridge between the brain and the peripheral nerves. J: So you're saying that the spinal cord is what connects the brain to the peripheral nervous system? M: Indeed I am John. The spinal cord carries impulses from the peripheral nerves up to the brain. J: The brain then conducts a response which travels back down the spinal cord and to the peripheral nerves. M: This concludes our report on the spinal cord- back to you Jerry. J: Thanks John and Mary. Well, that wraps up the central nervous system. I am going to send you over to Meghan and Jack, who have just traveled down the spinal cord and have arrived in the peripheral nervous system.

M: Hi again guys! I am in the peripheral nervous system, which can simply be defined as all of the nerves that are outside of the central nervous system. J: The peripheral nervous system consits of nerves that branch out from the central nervous system and connect it to the rest of the body. The peripheral nervous system is involved in both involuntary and voluntary actions.
 * EIGHTH SLIDE:**

**NINTH** **SLIDE:** M: 43 pairs of nerves make up the peripheral nervous system. 12 pairs of nerves originate in the brain. The other 31 pairs, the spinal nerves, begin in the spinal cord. J: One nerve in each pair of nerves goes to the left side of the body and the other nerve goes to the right side. M: The nerves of the peripheral nervous system can be divided into two groups, the somatic and autonomic nervous systems. J: The somatic nervous system controls voluntary actions, such as using a fork or tying shoes M:The autonomic nervous system control involuntary actions, such as digesting food. Back to you Jerry

J: And a final thanks to Meghan and Jack. Well, that is all we have today on body system news. Join us tomorrow when we will be talking about the skeletal system! Goodbye and thank you for watching!
