Review 1.What system’s function is to produce antibodies that protect us from disease-causing organisms? 2. What type of cell is responsible for fighting disease-causing organisms? 3. Where does this cell travel in our bodies? 4. What is another name for a disease-causing agent? 5. What are the two main functions of the nervous system? 6. What are the three main structures of the nervous system. Make sure you specify which nervous system they make up (CNS vs PNS.)

THE NERVOUS SYSTEM

Key Point #1: The 3 structures of the nervous system are: Central Nervous System (CNS) – Brain – Spinal Cord Peripheral Nervous System (PNS) – Nerves

Key Point #2: The 2 main functions of the nervous system are to… Function #1:use electric impulses to control all of the body’s processes, including involuntary and voluntary actions. – Involuntary – breathing, digesting, heart rate – Voluntary – walking, thinking, feeling Function #2:sense the environment – Smell, taste, touch, hear, see

How does the nervous system work?

Put this process into words You see a delicious piece of cake that you want to walk toward to eat. – Your eyes are a part of your nervous system and allow you to __________ the environment. Your brain (_________ nervous system) processes this information and you decide you want to walk toward the cake to eat it. That electric impulse to move travels down the spinal cord (_____________ nervous system) to the nerves (____________ nervous system) in your leg to cause your leg muscles to move your bones.

You try it! Your mom turned the stove on without telling you and you accidently touch it. The nerves in your _________ allow you to _______ the environment and realize its very HOT! That message travels from your finger to your brain (___________ __________ _____________) and you realize its very HOT! Another message travels from your brain to your hand and you ___________ _____ __________. THIS IS HOW YOUR NERVOUS SYSTEM PROTECTS YOU FROM HARM!
