  3. Role the Nervous system • The role that the Nervous system plays is extremely important because it carry`s the messages from the brain to all parts of the body. This is what allows us to move. Nervous system includes the brain and spinal cord.

  4. Major organs in the nervous system • The major parts of the Nervous system are the spinal cord and the brain. • Your spinal cord is a long white bundle of nerves that is connected to your brain. There are two main types of nerves that make up the spinal cord; sensory nerves and motor nerves

  5. The Brain • The brain is an essential part of your survival. Nerves reach from your brain to your face, eyes, ears, nose, and spinal cord, which controls movement and all senses.

  6. The organs in the nervous system work together • The organs in the nervous system work together by sending messages and triggers through the body to help with movement. The brain sends out these signals to the spinal cord and the body responds accordingly.

  7. Hot Stove • When a part of your body makes contact with something excessively hot or cold, you immediately withdraw your hand. This happens because, heat and pain receptors in the skin sent messages to the spinal cord, which were transferred to motor neurons that eventually connected to whichever part of your body that’s being effected from touching hot or cold.

  8. How is the nervous system connected to other body systems? • The nervous system is connected to the skeletal system because the nervous system sends signals to the spinal chord, which is one of the many bones in the skeletal system.

  9. The nervous system is also connected to the muscular system because when the brain informs the spinal system to move in a certain way, the muscle system is partially in charge of those movements. When the muscles contract, they move the skeletal system, which is a major part of the nervous system.

  10. Levels of organization in the brain • The brain is composed of several different types of tissues, like all organs. One type of tissue that the brain consists of is nerve tissue. Nerve tissue is made up of neurons (nerve cells) • The nervous system • The brain • Nerve tissue • neurons

  11. Name two disorders that affect the nervous system • Neuroscientist • A neuroscientist is a neurobiologist (someone that works with the nervous system) that works with brains. • Neurosurgeon • Someone that does surgery on the nervous system (especially the brain).

  12. Name 2 disorders that affect the nervous system Ataxia • Is a disorder that makes you have less coordination. • Epilepsy • Is a condition in the brain that makes people more prone to having seizures.

  13. How to maintain a healthy nervous system • Eat a well-balanced diet and drink lots of water and other liquids. Don’t use cigarettes or other tobacco products.

  14. five did you know facts about the nervous system • One- the brain stems job is to take care of the things we don’t think about, but are crucial to our survival, such as breathing or our heart rate. • Two- The spinal cord runs from the brain down to just below the ribs. • Three- If there is no blood flow, then there is no oxygen and that part of your brain can actually die. • Four-The weight of the human brain is about 3 lbs. • Five- The spinal cord is the body's main nerve trunk.- It is about 18 inches long.
