Document Content and Description Below

1. The function of the nervous system is to integrate and control the other body systems. Explain how the nervous system does this. " The nervous system receives and processes information and ... sends out signals to the muscles and glands to elicit an appropriate response. In this way, the nervous system integrates and controls the other systems of the body. " 2. List the 2 parts of the central nervous system. brain & spinal cord 3. How are the parts of the central nervous system protected? the brain is protected by the skull the spinal cord is protected by the vertebrae 4. How do the central nervous system and the peripheral nervous system interact? The central nervous system sends signals to and receive signals from the peripheral nervous system. 5. What is included in the peripheral nervous system? all nerves not in the brain or spinal cord such as the cranial nerves 6. What are the 2 divisions of the peripheral nervous system? sensory division and a motor division 7. Describe the movement of nerve impulses in the peripheral nervous system. The peripheral nervous system receives impulses from the sensory organs via the sensory division and then sends the impulses from the central nervous system to muscles and glands via the motor division. 8. What are the 2 divisions of the efferent division of the peripheral nervous system? somatic system and the autonomic system. 9. What is controlled by the somatic and autonomic nervous systems? The somatic system nerves control skeletal muscles, skin, and joints. The autonomic system nerves control the glands and smooth muscles of the internal organs and are not generally under conscious control. 10. What are the 2 divisions of the autonomic nervous system? sympathetic and parasympathetic nervous systems. 11. What is the function of the sympathetic nervous system? it activates and prepares the body for vigorous muscular activity, stress, and emergencies 12. What is the function of the parasympathetic nervous system? it lowers activity, operates during normal situations, permits digestion, and conserves energy Problem Set 1 1. The nervous system receives and processes information and sends out signals to the muscles and glands to elicit an appropriate response. In this way, the nervous system integrates and controls the other systems of the body. 2. The central nervous system includes the brain and the spinal cord. 3. The skull protects the brain and the vertebrae protect the spinal cord. 4. The central nervous system can send signals or impulses to and receive impulses from the peripheral nervous system. ................................................CONTINUED.........................................
