3. www.juniorscience.ie OB29describe the role of the central nervous system and the sensory and motor functions of nerves the role of the CENTRAL NERVOUS SYSTEM (CNS) is to control all the actions of the body This CNS has been preserved for display in a Science museum

4. www.juniorscience.ie OB29describe the role of the central nervous system and the sensory and motor functions of nerves … the CNS is made up of the brain and spinal cord… the brain takes up most of the space inside the skull the spinal cord is found inside the backbone

5. www.juniorscience.ie OB29describe the role of the central nervous system and the sensory and motor functions of nerves …nerve cells carry information between the CNS and every area of the body… …nerve cells are very long narrow cells… …the are two types of nerves cells: 1.SENSORY nerves bring messages from the sense organs to the CNS 2.MOTOR nerves bring messages from the CNS to the muscles of the body

6. www.juniorscience.ie OB29describe the role of the central nervous system and the sensory and motor functions of nerves …the sensory function of nerves is to gather information and take it to the CNS… sight smell taste touch sound

7. www.juniorscience.ie OB29describe the role of the central nervous system and the sensory and motor functions of nerves …the motor function of nerves is to take messages from the CNS to the muscles… “round of applause please”
